Emergency Food.

We ALWAYS send food the day we receive your order. However, sometimes the morph occurs quickly, and people become surprised by how fast it occurs. In the event that your tad has morphed into a little frog with a long tail, it is very important that it eats. An excellent “emergency food” is raw, uncooked chicken liver. It is very bloody and the frogs are attracted to it. PLEASE feed the ABSOLUTE smallest piece possible (we are talking pin head size) to your frog, twice a day, until your Stage Two Food arrives. Caution: if the piece of liver is too big your newly morphed frog will not be able to eat it, or worse, choke on it…please use the absolute smallest piece you can slice.

Category: Emergency


Growafrogs should be fed Stage Two Food twice daily, once in the morning and once in the evening. If they are hungry, they will eat. It’s lots of fun to watch your frog enjoy it’s food!

If you don’t see your frog eat, in 99% of the cases it just means that your frog is not hungry at that moment. Your frog WILL eat when it gets hungry. You may help your frog eat by feeding Stage Two Food directly above your Growafrog’s eyes. Growafrogs have very poor peripheral vision, but the have fantastic vertical vision. Your frog can easily see it’s serving spoon, Stage Two Food nuggets and you (if you in the field of vision directly above your frog’s eyes)! Although your frog has poor peripheral vision, it WILL locate food which it cannot see by it’s fantastic olfactory and vibration senses!

Hiding Places.

Growafrogs are aquatic animals and need to remain moist. If your Growafrog it allowed to leave it’s water habitat, it will attempt to seek dampness and water. Time is definitely of the essence. Look for your Growafrog in the bathroom ‘behind the commode.’ It will also likely end up in a corner of the room, or under a piece of furniture.

In an emergency, humidity is your frog’s friend. The amount of moisture in the air plays an vital role in determining how long your frog can remain out of water and not suffer any harm. In very hot, dry weather/arid climates your frog cannot even survive 10 minutes out of water. On the other hand, in damp, muggy, somewhat cool weather, they may survive for days…especially if the find some kind of water. Please keep looking for your frog! When you find it, put it back in it’s aquatic habitat.

Category: Emergency

Holding Each Other.

Grow-a-Frogs are very friendly. Although it may look as if one frog (the male) is trying to hurt the other frog, they are actually just holding each other. Sometimes, this behavior can be an indication that the female is ready to lay eggs. Don’t worry at all… this looks like it an ’emergency’, but it certainly is not.

Order Tracking.

First of all, please look in your mailbox to see if there is a small piece of paper that says “NOTICE OF ATTEMPTED DELIVERY.” In many cases, your letter carrier has attempted to deliver the package and it is at your local Post Office.

Food orders, unless received on Sunday, are ALWAYS sent the same day we receive them. Tadpole and frog orders are sent at the beginning of the week. If you cannot locate your order, please either call the Gilly Hotline at 352 544 0333 or E-mail at thrrivbk@aol.com us so we may inform you as to the status of delivery and/or provide tracking information.

Category: Emergency

Express Delivery Option.

Please call the Gilly Hotline at 352 544 0333 before 2 P.M. Eastern Time, and we will make every effort to “get it there tomorrow”. Please note that due to the very high cost of overnight, we must charge an additional minimum $35.00 (costs could be much higher for larger, heavier orders). Overnight delivery in the Continental U.S. only. We regret that there are no longer Sunday deliveries by any major services. Any “NEXT DAY AIR” packages ordered on Saturday will arrive Monday morning. Also, there is a $15.00 additional surcharge for Friday orders requesting Saturday morning delivery.

Use The Spring Water Bottle.

The clear gallon, half gallon, or liter plastic bottle your spring water comes in makes an excellent emergency tadpole home.

Just cut the top off with a safety scissors if your Tad-pool (which is the clear, plex-aquarium that comes with the Original Growafrog Kit) becomes lost, misplaced, broken, contaminated, or just plain unavailable.

Feed your tadpole one level spoon of Stage One Food daily. You may even put the Nutri-rocks and Deco-plant in there. If your Tad-pool has just been misplaced (and it is NOT contaminated by aerosol air fresheners or pesticides), then just pour the water AND the tadpole back into the Tad-pool.

Category: Emergency

Tadpole Rearing Instructions – Quick Overview.

Use only bottled Spring Water to grow tadpoles. NEVER use tap water. Make sure source of the spring appears on the label of the bottled water (labeling tends to be confusing). Fill the Tad-pool with spring water. Leave an inch or so airspace at the top so your tadpole can breathe. Feed one LEVEL spoon of Stage One Food every day. Change 1/4 of the water once a week with bottled spring water. STOP feeding Stage One Food when the front arms emerge. START feeding STAGE TWO Food when your tadpole has about a 1/2 inch tail and looks very much like a frog.

Category: Emergency

Emergency Substitution For Spring Water.

First of all, do NOT use tap water for tadpoles. It is a much better idea to leave your tadpole in the water that it came with than to use any kind of tap water. If you notice that the bottle says ‘purified water’, or even distilled water, it is in MOST cases O.K. to use that water until you can get some spring water. Purified water may, and distilled water does lack ions necessary for your tadpoles health and well being… however, a few hours in this water will not be harmful in most cases. Replace the purified or distilled water with spring water at your earliest convenience.

Category: Emergency

Tadpole Health.

Your Grow-a-Frog tadpole(s) leave our facility in optimal health. It is normal for them to become lethargic during metamorphosis, as many metabolic changes are taking place. If your tadpole seems a little listless please immediately change 1/4 of the water in the habitat with bottled spring water. Keep your tadpole at room temperature 68 – 72 degrees. If you KNOW that there is a problem, such as if someone has either put soap or sprayed insecticide in the room, then place your tadpole into the spring water bottle.

Category: Emergency

Adjustment Period.

Your Grow-A-Frog tadpole will need a little time to adjust to it’s new habitat. The ‘normal’ tadpole swimming position is ‘head down – tail up.’ It takes up to 24 hours for tadpoles to become adjusted to their new ecosystem and any changes in temperature. Likely your tadpole will be just fine.

Bi-ol-o-gy is defined as the scientific study of living organisms.

Fortunately, nature has provided us with an incredible way to study amphibian development without dissection – see thru Pipidae tadpoles.

Study life! Watch a LIVE heartbeat!

The only ‘equipment’ you need is your observation skills – perhaps a magnifying glass or digital camera – and a desire to learn about living organisms.

By the way, if you are using a digital camera which has a MACRO (sometimes called a tulip or flower mode) – then use the macro setting. It will allow you to focus on smaller objects like your tadpoles with far greater detail.

The average lifespan of a Growafrog is 5 years. That is to say, most Grow-a-frogs live about 5 years. However, in some instances they CAN and DO live much longer. We receive letters and E-mails from customers with 20+ year old frogs! We still do not know how long they can live…time will tell! If you have a Growafrog that you’ve had for quite a while, please let us know. We’d love to hear about your frog!!

You’ll Be Surprised What You Can Learn From A Frog!

The first thing you’ll notice about your Growafrog is that it looks a lot more like YOU than a fish! It has arms and legs, a definite head and ‘fingers.’ Can you talk to your frog? Sure – but did you know your frog will listen to you? That’s right. Your Growafrog will respond to your voice! Go ahead and sing to your frog. The incredibly complex lateral line organ (the ‘stitching’ on the edge of your frog’s back) is a vibratory sense organ soo sensitive that it can recognize YOUR voice ! You CAN talk to your frog (like you would talk to a dog or cat) AND your frog will LISTEN and respond – sometimes by shaking it’s head or nodding at you.

Category: Frogs

Wow… They Are Soooo Friendly And Playful!

You will LOVE to feed your frogs! Your frog will swim right towards you and jump up to stick it’s head up and out of the water to greet you!

Apartments and Condo’s.

In most cases, you most certainly can have a Grow-a-frog in your apartment or condo at the completion of a school project. Indeed, they make ideal companions especially if you cannot have a dog or cat. Sometimes, an upper floor ‘unit’ is not allowed to have even a larger fish tank (or water bed!) due to weight considerations… but a Grow-a-frog is fine. Definitely check with your landlord or lease ‘to be sure’, but in most places this is not a concern at all.

Category: Frogs

Sexual Dimorphism.

Growafrog females are different in appearance from males. Females are generally larger than males. The sides of their body are also naturally ‘puffed out’ from ovaries filled with eggs – giving them a more pear shaped look. In the frog world, females are always ‘with eggs’, or gravid, so it makes sense that they are larger than males. Females have a cloaca, which is a protrusion where the eggs emerge. It is noticeable. Males do not have a cloaca. Males have black ‘nuptial pads’ on the inside of their forearms. Females do not have black ‘pads.’

Category: Frogs


Just as there are short and tall people, there are large and small frogs. If you have a very small frog, it may be a male. Yet even among males, there is great variation in size. In general, smaller frogs breed just as well as their larger counterparts, although smaller females do not lay as many eggs. Their longevity and health are the same as larger frogs.

Category: Frogs


Growafrogs mature to an average body size of about half a dollar bill. Males, in general, are about half the size of females – so their full grown body size (not including arms and legs) as adults will be less then half a dollar bill. Of course, like people (and all animals) there is some variation to this!

Some frogs are larger and smaller than average just like some people are larger or smaller than ‘average.’ Also, unlike people, Growafrogs continue to grow throughout their lifetimes… so the older the frog – the bigger the frog.

Category: Frogs


The single most important factor in your frog’s well being is its environment. We cannot overemphasize the basic. Keep the temperature away from extremes (keep below 85, and above 60 degrees F). Keep all insecticides, household sprays and foreign objects such as pencils and pens OUT of the frog’s habitat. We also highly recommend minimum weekly 1/4 partial water changes (even if you use a filter). We also highly recommend that you use Water Crystals to purify tap water, keep the oxygen level low, keep aquarium gravel (choking hazard) out of the habitat, use a sandy substrate for the bottom such as Growafrog Habitat Soil, feed your Growafrog laboratory grade Stage Two Food, and keep aquarium fish out of your frog’s habitat.

Having said all of that, Growafrogs can and do get sick. The most important things you can do if your frog is obviously sick is to do a partial 1/4 – 1/2 water change. Water quality is the number one most important factor in keeping your Growafrog healthy. If your frog does get ill, please send us an E-mail describing the problem, and we’ll try to help. We do have a medicated food (it has an antibiotic in it) which can treat a wide variety of infections and diseases. It is available by calling the Gilly Hotline at 352 544 0333.

Category: Frogs


Growafrogs are Pipidae frogs, which in nature originally come from South America and Africa. However, your Growafrog tadpole has never been to Africa or South America. All of our tadpoles and all of our breeder stock are born and captive-bred in our facilities in Brooksville, Florida. We do not have a single frog which has ever been to Africa or South America. All Growafrogs are ‘Floridians’ grown in pure crystal clear well water from an underground spring in Brooksville, Florida. Our water source shares the very same aquifer that the ‘mermaids’ swim in at the world famous Weeki Wachee Springs Mermaid Show!

Category: Frogs


It is an unusual event for Growafrogs to mate and have eggs that develop into tadpoles, but it can happen. Of course, you’ll need a female and a male. Sometimes the females will lay eggs without a male, but, we’re sorry, they will never develop.

If you are among the lucky ones who experience a successful mating, the first thing you should do is to remove the adults, or they will ( yikes!) eat the eggs !! Please send us an E-mail and we’ll be more than ‘hoppy’ to congratulate you and help you raise your eggs into tads and frogs. Of course, if you do not want to grow any tadpoles simply do ‘nothing.’ Your adults will eat every egg and/or newly hatched larvae in a few hours or less.

Category: Frogs

Peripheral Vision.

Your Growafrog senses food by sight, smell and vibration. Your Growafrog does NOT have to see it’s food at all to eat. Your Growafrog has an extremely keen olfactory sense and ‘vibration’ sense (those lateral line ‘stitches’ on the back of your frog are a vibration sensory organ).

Although Growafrogs do not have good peripheral vision at all, they have fantastic vision ‘just above their eyes’ as they are always looking up. To demonstrate this, try feeding your frog’s Stage Two Food above it’s eyes. Just position the little serving spoon above frog’s head so your frog can see it’s food within it’s straight up range of vision. Your frog may literally jump up out of the water to greet you! They are soooo friendly when they can see you in their ‘line of sight.’

Category: Frogs


If your frog ‘sings’, its a boy. The ‘singing’ is really a ‘mating call.’ They sometimes sing during the day, but they usually sing in the middle of the night. Also, it seems to be ‘frog specific.’ Just like people, some sing all the time… while others hardly sing at all.

Category: Frogs


In the Growafrog world, girls are about twice as big as boys. The females lay the eggs, and need to be larger so they may carry eggs. It is actually easier to tell the boys from the girls, though. Male Growafrogs have very distinct black markings on the inside of their arms. It kind of looks like someone took a big black marker and made a bold stripe on their forearms. Also, if it makes and sounds at all, its a boy… cause ‘only the boys make noise.’

Category: Frogs

Wet At All Times.

We highly recommend that you do NOT ‘net’ your Growafrog!

Growafrogs need to remain moist at all times. They are also very quick and can simply get out of the net. Even very short periods of time out of water can be harmful!

If you need to move your Growafrog, the preferred way is to ‘pour’ at least some of the water from the habitat along with your frog. Another method to move your frog is to simply remove most of the water from the habitat – then ‘scoop’ your frog and some water from the habitat into either a small pail which has never been washed with soap or a disposable ‘drink cup’ (rinsed and dried with a paper towel ) from your favorite convenience store.

Category: Frogs


Just as you would pet a dog or cat, it is OK if you interact with your frog every now and then. It is best to use the little serving spoon to ‘feed and play’ with our frog and to not put your hands in the water directly. Please remember to practice good hygiene and wash your hands with soap and water after you play with your frog, in much the same way as you should wash your hands with soap and water after coming in contact with a dog or cat.

These days, there are all sorts of reasons for children and adults to get into the good habit of washing hands! We recommend that you wash you hands with soap and water each and every time you come into contact with your frog or any portion of the habitat including your tadpole or frog’s water, tadpole and/or frog food… even the serving spoon. The current recommendation is to wash your hands with soap and water for 20 seconds or ‘as long as it takes to sing Happy Birthday To You’ all the way through, twice.

Parents and Teachers are encouraged to use Growafrog as a hygiene lesson! Did you know that the acronym F.R.O.G stands for Friction Rubs Out Gems in Surgery Centers across the USA? That’s right! Did you ever see a television program where the surgeon scrubs their hands? Of course you have! There’s a reason for this… it’s because people need to get rid of any germs! Wash your hands with friction… rub’em hard together… To disloged all of those germs from your outer skin. Now, run your hands under warm water FIRST… then add soap after wetting your hands not before. Dry by RUBBING your hands with a paper towel. What a great way to associcate washing your hands after contact with Growafrogs with ALL good hygiene practices every single day! Students – remember F.R.O.G stands for Friction Rubs Out Germs. Wash you hand with friction ALL the time!

Please recycle! The old, dirty water from your frog’s habitat may be used as a plant fertilizer ! We recommend disposing the old water outdoors, preferably as a plant fertilizer to recycle it. NEVER pour the old dirty water down the kitchen or bathroom sink.

Good hygiene is Good!

Moisture Required. This is probably a bad idea. Growafrogs need to remain moist in order to survive. They should not be out of water. You would be harming your frog if it is out of water for more than a very brief period of time. They need to remain in water.

Category: Frogs

Habitat Description.

We recommend that you do not keep your Growafrogs with fish, as Growafrogs are lung breathing amphibians. In their natural habitat, they live in small ponds that have still water and very low oxygen levels. In order to respire, Growafrogs come to the surface and take a breath of air.

Fish, on the other hand, respire with gills. They extract oxygen from water… and do not surface for air. In an aquarium, fish typically need an air stone or other device that produces ‘thousands of tiny bubbles’ – which increase the oxygen level in water.

These habitats are often not compatible with each other, as the oxygen levels necessary to maintain fish may actually harm your frog. Very high oxygen levels are harmful for your frog… and very low oxygen levels are harmful to fish.

Also, remarkably disease-free Growafrogs tend to get diseases that are not ordinarily acquire when they are kept with fish. It is best to keep Growafrogs in a separate habitat.

An ordinary 10 gallon (or larger) aquarium is an excellent home for Growafrogs if you choose to use them for frogs only, and not for fish and frogs. We would suggest that you either use a ‘high cover’ such as our Shade Domes or keep the water level 4 inches from the top. Also, we highly recommend Habitat Soil as an excellent substrate bottom for your Growafrogs in a 10 gallon tank. Our 6 lb. size is plenty enough for a 10 gallon tank. Our little Growafrog filter is specifically made for Growafrogs and will work great in an aquarium. It is a ‘sponge type’ filter and completely adjustable to the height of your aquarium and water level. You may keep a snail in the habitat if you wish as they are compatible with your Growafrogs.

Category: Frogs

Replenishment Water Temperature.

The best water temperature for changing the water is your frog’s habitat is room temperature 68 – 72 degrees.

We recommend that you allow the water to equilibrate to room temperature by letting it sit for an hour or so before using it.

If this is not practical (or even if it is) use water from the COLD faucet, only. Luke warm temperatures (85 degrees or above) can be LETHAL to your frogs! The water does not even need to be ‘warm to the touch’ as especially in summer it is difficult to tell water temperature just by putting your hands under the faucet.

We would much prefer to be ‘safe than sorry’ – so our suggestion is to use water from the COLD faucet only. Let it run for a minute or two (especially in summer) – then let it ‘sit’ to adjust to room temperature.

Category: Frogs


The best temperature for your Growafrog is normal, household temperature… 68 to 72 degrees Fahrenheit.

Growafrogs can stand a much wider variety of temperatures. Please do not become alarmed at all if the temperature goes somewhat above or below this range.

In summer, keep your frog ‘as cool as possible.’ Preferably, keep in either an air conditioned room, a cooler room in your home, or a cool basement. Do not use a heater for the water at all! It is very important that you do not keep your frog in direct sunlight… especially in summer. Even if the air temperature in your home is in the 70’s, the temperature in your frog’s habitat could reach 100 or more (due to the greenhouse effect) if your frog in the window with direct sunlight. This caution makes a lot of common sense… it is the same reason why you should not keep pets in a car with the windows up – especially during the summer.

In winter, keep the temperature of the water at normal room temperature. Even if your thermostat is ‘turned down’ your Growafrog will be just fine as long as there is ‘some’ heat on in your school or home on the coldest days. Of course, if a window is open and the temperatures are extremely cold – just close the window.

Category: Frogs

Aquatic Habitat.

Growafrogs are not like ordinary frogs. They are aquatic throughout their lives. They always live in the water. They do not need, or ‘want’ to be on land. Furthermore, they will be greatly harmed if they remain dry for even relatively short periods of time. Please keep your Growafrog in water all the times.

Category: Frogs

Growafrog Filter.

The choice is up to you, but as a general rule, we advise that ‘the bigger the habitat, the more you need a filter.’ Our Stage Two Super Offer, which is the same habitat as our Tadventure Kit, is ‘desktop sized.’ We feel that it is easier to just change the water once or twice a week with our EZ Clean lid (its included in the Stage Two Super Offer) than to use a filter. Stage Two Single and Double Tube Towns are available with and without our optional filter.

If you have a larger habitat, nothing beats our ‘pretty little Growafrog filter.’ Growafrog filters should be used with Habitat Soil and weekly 1/4 partial water changes to keep excellent water quality for your Growafrogs. Designed to be Growafrog-safe and incredibly easy to use, Growafrog filters may be used in ANY size tank up to 10 gallons as they are totally adjustable. They’re pretty (your color choice of Dew Blue, Gilly Green, Ribbit Red, Leap’in Lemon, Hop’on Orange, SplashBlack, WhiteHouse, or Pop’n Purple) very inexpensive, very easy to maintain, and they work ! There are NO cartridges’ that need to be changed, either… simply rinse the sponge! If you are keeping your Growafrogs in an aquarium larger than 10 gallons, we have an aquaculture grade sponge filter which we use here and highly recommend. Email us at thrrivbk@aol.com the size of your tank and we’ll make sure that you get the right sized filter for your setup.

Also, and this is very important, we highly recommend weekly 1/4 minimum water changes weekly. A filter is not at all a substitute for weekly partial water changes. Filters can and do help to keep the water cleaner and break down wastes – no doubt – but there is not a filter in the world which is a substitute for partial water changes. Partial water changes are sooo easy to do and so great for your Growafrog’s well being. Please do not be ‘lulled’ into thinking that because you have a filter you do not need to do a water change. Even in nature it rains!

Category: Frogs

Water Changes.

Your frog’s water should be ‘refreshed’ by doing a 1/4 water change approximately once a week. A small partial water change will vastly improve water quality AND the health of your frog. Good water quality is the ‘secret’ to keeping your frog happy and healthy. If your habitat tends to get dirty, then you’ll need to do up to a 90 percent water change once a week. If you happen to have a Stage Two Habitat, this can be done in about one minute. Just pour out all the dirty water (use the snap on EZ clean lid included at no charge in your Stage Two kit) while you keep your frog inside the habitat… then just pour in tap water treated with Water Crystals.

By the way, if you have house plants – you may want to take advantage of the fantastic ‘fertilizer’ that you may be pouring down the drain. Your frog’s old water is an EXCELLENT plant food… and extremely easy to use… just use the frog’s old water to water your plants! If you happen to have an EZ CLEAN Lid, it is even more simple than you can probably imagine – just remove the dome, ‘snap on’ the EZ CLEAN Lid… pick up the frog and all of the water inside…turn the Stage Two Habitat (with the frog inside) upside down… and go water your plants ! Your frog will appreciate the water change, and your plants will thrive. Also, the EZ CLEAN lid fits very neatly in the bottom frame of your Stage Two or Tube Town Habitat… so it is neat, practical, and ecological, too.

Another ‘tip’ you may try is to use a disposable plastic or paper cup to ‘dip out’ some water. We use the large, paper or plastic beverage cups from fast food restaurants and convenience stores (don’t worry about the beverage that was in it… the residue from drinks… even diet soda… will not hurt your frog at all).

Just dip out some old water, and pour in the new.

We highly recommend ‘partial water changes’ in all of our habitats. At the very least, keep at least some of the Habitat Soil and a little of the old water when you do a water change. Do not change all of the water and rinse the Habitat Soil completely. Habitat Soil contains ‘beneficial bacteria’ which is very important for water quality. If you are starting a new habitat try to fill it with spring water for the first time so that beneficial bacteria have a chance to grow. If this is not practical at the very least empty the Habitat Soil from your old tank into the new tank, and at least some of the old water, too.

Category: Frogs

Water Crystals.

Growafrog Water Crystals are very powerful water purifiers that allow you to safely use ordinary tap water for your frogs. Please remember to treat tap water with Water Crystals BEFORE you put the water in your frog’s habitat. As good water quality is sooo important to your frog’s health, we offer Water Crystals very inexpensively. The Large Size seemingly ‘lasts almost forever.’

Category: Frogs

Habitat Lids or Covers.

Habitat Covers and lids are recommended for frog habitats for a variety of reasons. Growafrogs are ‘semi nocturnal’ and prefer the natural comfort of shade to sun. Also, Growafrogs become ‘active’ and ‘jump’ during low pressure atmospheric events such as thunderstorms. If you see your frog ‘jumping’ up and down, there is no need to check the barometer you have a low pressure atmospheric event on it’s way. If the water level is your frog’s habitat is very close to the surface and you do not have a ‘high’, tightly fitting cover on the habitat – your frog could jump out !

When your frog ‘jumps’ it simply does not at all know that there is no water on the other side of that ‘jump.’ Over the years we have heard countless stories about frogs which have ‘escaped’ from their habitats. We highly recommend that you use a ‘high’ ‘tailored fitting’ lid or cover with no ‘escape holes’ such as Growafrog Shade Domes. Shade Domes are available in pairs and two Shade Domes will fit any ordinary 10 gallon aquarium. If you choose to use another cover that’s fine… just make sure that it is ‘tight fitting with no holes’ as over the course of time your Growafrogs could ‘find’ these holes and escape. If you choose not to use a lid, we suggest keeping the water level about 4-5 inches from the top of your habitat. Your Growafrog cannot jump much higher than that!

All of our Growafrog Stage Two Habitats include covers at no extra charge. Our Tadventure and Tadpole Tube Town Kits include dome covers at no additional cost. The Larger Growafrog Tadpole Habitat does not include a dome cover however they are available at nominal cost for use after metamorphosis (or for tadpoles if you happen to have an ‘inquisitive cat’). Our BIG ‘n Hoppy and Tube City Plexiglass habitats include a ‘comfort’ Shade Dome Cover at no extra cost. If you choose to put your larger Growafrog in an ordinary aquarium, we highly recommend that you either use Shade Domes or keep the water level at least 4 inches from the top. Growafrogs are totally aquatic and do not need or ‘want’ land at all. Indeed, if they do leave the water and go on to land they cannot survive long at all unless they remain very, very moist.

Category: Frogs

Habitat Soil.

Habitat Soil is a wonderful addition to your frog’s habitat. In many ways, it is important as food, as it keeps the frog happy by providing a natural ‘sandy’ bottom – just like that in any pond or lake. It also vastly improves the water quality in your Growafrog’s home by providing places for beneficial bacteria to grow.

We suggest that you do not use ordinary aquarium gravel for Growafrogs. Small rocks from aquarium gravel form a choking hazard for Growafrogs – in much the same way as chicken bones are a choking hazard for dogs.

Category: Frogs

Wink & Blink.

It’s wonderful how much you can learn about your Growafrog when you give it a ‘closer’ look. Every time your frog swallows a piece of food it also closes it’s eyes and ‘blinks’ as a ‘reflex.’ Kind of like how you always close your eyes when you sneeze, your Growafrogs close their eyes when they swallow! We like to think they’re winking as a way of communicating a big ‘thank you’ for serving them food… but that’s anthropomorphism for sure – your frogs wink even if you are not around at all.

Category: Frogs

Froglet Feeding Quantity.

Your Growafrog should eat ‘as much food as can been eaten in 15 minutes.’ Typically, a newly morphed frog will eat one nugget in the morning, and one in the evening. Month old frogs will eat 2-3 nuggets per feeding. As your Growafrogs mature, you’ll need to increase their food consumption. It is kind of like feeding any other pet. Simply observe how much they eat, and offer more food if they are still hungry. Older frogs may usually be fed with 1/4, 1/2, 3/4, or full serving spoons of Stage Two Food as a meal.

Category: Frogs

Froglet Feeding Schedule.

Growafrogs should be fed once in the morning, and once in the evening. It is better to feed a little food, twice a day, than to feed a lot of food all at once. This ensures that you will know your frog is eating and will not waste food.

Category: Frogs

Froglet Feeding.

Growafrogs begin to eat Stage Two Food when the morph is almost complete and they look ‘like a little frog with a 1/4 to 1/2 tail.’

It is very important to feed your frog when the tail is STILL there. Growafrogs begin to eat Stage Two Food when they still have a tail, although the ‘exact’ time varies for individual frogs. They always begin to eat before the tail is gone, even if the ‘tail’ is just a little ‘stub.’

Category: Frogs

Froglet Food.

Growafrog frogs eat Stage Two Food. This 100% nutritionally complete diet is the same high quality food we feed to our Growafrogs in our facility. They may also eat small pieces of earthworms or beef heart.

Every time you order Stage Two Food, you will also receive a little ‘serving spoon’ to feed your frog. The Growafrog ‘serving spoon’ is more than convenient, it is also highly functional. When you ‘wave’ your frog’s ‘serving spoon’ straight up above the eyes, your frog can see the food. Growafrogs also feed by olfactory and vibration senses. Your Growafrog does NOT have to see the food to eat. However, feeding directly above the eyes with the ‘serving spoon’ reduces waste! Your frog’s habitat will stay cleaner as uneaten food clouds the water. You’ll save money by not overfeeding… and it is simply more ‘fun’ to interact with your frog when it gets ‘spoon fed.’

Frog – Froglet ‘Share’ Care.

Grow-a-Frogs are very social animals. Growafrogs very much enjoy the company of other frogs and your company, too. We highly recommend that you keep two (or more) Growafrogs together in the same habitat. We even have a Frog ‘Buddies’ kit which encourages Growafrog enthusiasts to keep two frogs together.

Frogs of ‘approximately the same size’ have no problems at all being together. Adult Growafrogs NEVER have any problems with other, adult Growafrogs.

However, if there is a BIG size difference between the frogs, the larger frog could turn aggressive towards the smaller one especially when they are first introduced.

Pay particular attention to this concern if you have a newly morphed froglet ready to be introduced into a habitat with an older, larger frog. If you had a small frog that’s ‘bite sized’ compared to the much larger frog, please follow the next introduction directions.

Introduction Directions:

Just like people, Growafrogs froglets form faster, more friendly relationships when they are properly introduced.

Frog friends must be properly introduced before the may share the same habitat. This simple procedure involves keeping frog friends in separate habitats, side by side, so they can see each other and become familiar with each other. Be sure to keep BOTH frogs well fed.

After 48 hours, you may place them both in the same habitat and OBSERVE THEIR BEHAVIOR. If the two frogs seem to be getting along, then you have made a successful introduction. If they are behaving in an unfriendly or aggressive manner, it is best to wait until the little guy grows up a bit. Put the little guy in a separate habitat and fatten him up. Remember, Growafrogs are never aggressive towards each other UNLESS one of the frogs is ‘bite sized.’ Caution: In some instances the aggressive behavior could actually result in the little frog being eaten by the bigger one! It is always best to err on the side of caution and keep the little one separate if it seems ‘bite-sized’ compared to the other. Growafrog do not have to be the same size to live together, you only have to make sure that one is not ‘bite-sized’ in comparison with the other. If the two frogs are of similar size, they will not harm each other.

Froglet – Tadpole ‘Share’ Care.

If you have ordered a TADventure Kit or Life Cycle Kit, you will probably have tadpoles AND froglets in the same habitat as they do not all morph at the same time. This is no problem at all, provided that the froglets are removed and placed into a separate habitat about 1 week after morphing. It is OK to feed tadpole AND Stage Two Food in the same habitat. You will probably need less tadpole food, as the tads remaining are likely to be near the stage when the front arms are out and they stop eating. It is not at all harmful to feed tadpole food in a habitat that has morphing frogs. Of course, your froglets do not eat tadpole food, but it will not hurt them at all.

If you have a TADpole Single or Double TubeTown, your already have Tube Caps which are specially designed to help grow tadpoles and froglets in the same habitat. Just ‘scoot’ the frog to one side of the habitat and cap the tubes to keep froglets and tadpoles separate. Please do not worry that you need to do this the ‘moment’ the tadpoles morph into froglets. You will have about a week or so to cap the tubes because the tadpoles are bigger than the newly morphed froglets. The froglets cannot hurt the tads all for the first week or so post metamorphosis – they are just too small.

Arrival Froglet Care.

If you have received a froglet from us, it is already morphed. It is at least a week or two past metamorphosis, so it may be placed right into a Stage Two Habitat,Tube-Town Habitat, or other habitat using Water Crystals. Growafrogs are pretty wonderful, hearty little guys, so if you follow the simple instructions of keeping them at room temperature and away from household sprays and pesticides, it should be fine.

Endangered Species Breeding Program.

Amphibian declines and extinctions are a huge worldwide concern. There is no ‘one cause.’ Lots of factors are contributing to this sad state of affairs, some of which may still be unknown.

Scientists around the world are literally in a race against time to help save these wonderful amphibians. However, time is running out.

We now offer an ‘in depth’ Amphibian Decline Lesson Plan at no charge to help teachers educate students about this immediate global concern.

Traditionally, Conservation efforts are centered around preserving habitats and lands for animals to thrive with limited human intervention such as parks, preserves, and designated wetlands. Development ordinances can also help amphibians and humans to coexist. However, today’s crisis was unforeseen as amphibians are disappearing at an alarming rate even from preserves, wilderness, undeveloped regions and rain forests…

Conservation efforts are now being focused on captive breeding of endangered amphibians. We will ‘try and do our part’ by breeding smaller Pipidae species endangered in their natural habitat and distributing them to as many classrooms as possible to help Save the Frogs!

Native Tadpoles.

It sounds simple. Everyone ‘growing up’ just went to the pond and caught tadpoles, so why not use them for classrooms?

Frogs typically breed in the spring… so most tadpoles are likely not ‘available’ in fall and winter months. If you are able to find native tadpoles during that time likely they are larger bullfrog tadpoles which can take up to two whole years to morph! If you are able to find young tadpoles or eggs in spring the morph typically takes two months or more. This varies considerably according to location and kind of tadpole… but the morph probably will not be completed before the end of the school year.

Of course, if your school is in a major metropolitan area there may not be any ponds, let alone tadpoles, near your school at all. Grow-a-frogs are a wonderful way for ‘city kids’ to have a positive ‘natural history’ experience with tadpoles in your classroom!

Sadly, there is a ‘disease of the frogs’ called Chytrid which can be lethal to native frogs and tadpoles. Chytrid is a relatively recent discovery and the Chytrid fungus is responsible in part for amphibian declines worldwide. It is with great sorrow that we need to say the seemingly harmless act of collecting tadpoles from the pond for nature study and re-releasing them after metamorphosis could actually contribute to the proliferation of Chytridiomycosis.

We want to be sure that your students do NOT spread this fungus! Your Grow-a-frogs are NOT affected by this fungus as they are captive bred and routinely monitored.

The study of amphibian metamorphosis is an integral part of nearly every K-8 curriculum. When you employ Grow-a-frogs in class for education, your students are observing a valuable lesson in life sciences and are also allowing native tadpoles in your region to remain where they need to be – in the pond.

When your anatomy lesson plans include transparent Growafrog tadpoles – your students are enriched with an unparalleled biology lesson and you are allowing native frog populations to remain undisturbed. Growafrogs are good for local frog populations and academic requirements!

Grow-a-frogs are wonderful tadpoles and frogs before and after the morph, but you should NEVER release your Growafrog or any other amphibian into the local environment even it came from there in the first place!

If you or your students are able to care for the froglets after the morph and will be responsible to never release them into the local ecosystem, then we highly recommend our captive bred see thru Grow-a-frog tadpoles. However, if you or your students are not willing / able to care for them after the morph then we highly recommend that you do NOT use Growafrogs. The release of any non native animal into your local ecosystem is a serious cause for alarm.

Please do not release any non-native animal or pet into the environment – ever!

Sometimes, unforeseen circumstances arise and you may not be able to keep your Growafrogs. This can happen for many different reasons. We want you to know that Growafrogs are relatively easy to care for and in all likelyhood you will be able to find a kind-hearted student, faculty member, family member, co-worker or friend to care for your frog. Also, we will ALWAYS welcome your frog back home! If you need breathable bags for safe journey ‘back home’ simply email us at thrrivbk@aol.com.

If you are using locally collected tadpoles for study, try and be sure that the local tadpoles are not from endangered frogs. Many endangered frogs are right here in the U.S.! We highly recommend that you visit the U.S Geological Survey tadpole page to help with identification. To prevent the spread of Chytridiomycosis, you may want to consider studying tadpoles in the pond without collecting them. If you are collecting tadpoles, make absolutely sure that these tadpoles are kept by themselves and never mixed with any other tadpoles or frogs at all.

As Educators, now more than ever it is imperative to inform your students about concerns of releasing any animal… and indeed any amphibian native or non-native into your local ecosystem. Pure and simple – Don’t let ’em go! When planning for care of native frogs in classroom post metamorphosis, please take into consideration that in nearly all cases you will need to provide a steady diet of live insects as most native frogs only eat live food. Most native tadpoles have relatively easy care requirements, but most native frogs have very demanding care requirements. Are you really going to keep that bullfrog or even grass frog in classroom and provide the spacial requirements and steady diet of live moving insects for the frog’s entire lifespan? If so, this is a wonderful thing to do and we encourage you to do so – but if you are planning to simply ‘let ’em go’ after the morph we urge you NOT to do so ! Survival of amphibians and the well being of the environment depend upon what your students learn now. You can and will make a difference for future generations!

Over The Weekend.

One of the ‘nice’ things about Grow-a-frogs for classroom use is that they can easily go ‘over the weekend’ with no ill effects at all provided the water in their habitat is partially refreshed weekly and they are otherwise well fed. You do NOT have to transport your Grow-a-frogs home to feed over the weekend.

If you happen to have someone who can feed over the weekend in school that would be great, but if not try and feed a little more on Friday ( perhaps 2-3 times a day if you can ) for tadpoles and froglets. However, do NOT pour lots of extra food into the habitat 5 minutes before you leave.

Underfeeding is preferred to overfeeding.

Keep away from large unshaded windows – especially in early fall / late spring – to prevent the habitat from getting far too hot from direct sunlight. Essentially, it is the same reason why you would not keep any pet in a car with the windows rolled up – it can just get far too hot.

Category: Classroom

Window Of Life.

Remarkably, yes.

Growafrog Pipidae tadpoles uniquely provide students and teachers with an incredible opportunity to study life during embryonic stages.

You cannot see an egg develop in mammals at all as mammals including humans (of course) have internal fertilization.

Amphibians have external fertilization, so you can see an egg develop and watch larval forms outside of the body with a simple magnifying glass or even the naked eye. However, transparent Growafrog Pipidae tadpoles are one of the very, very few life forms which allow you to study internal structures as they unfold by direct observation. Not only can you experience the miracle of metamorphosis, you also may quite literally see life’s organs develop. Watch the formation of the eyes, heart, brain, skin and digestive system as well as ‘interesting’ structures like tentacles and the remarkable lateral line system of these intriguing underwater amphibians.

Why dissect a frog? Your students will gain a far more important and informative biology lesson by observing a see thru living Growafrog Pipidae tadpole. You may literally dissect a Growafrog tadpole ‘with your eyes’ as NO dissection is required!

Next Day Air.

We can provide Next Day Air delivery. However there is a substantial additional charge as this service is inherently very expensive.

Please call the Gilly Hotline at 352 544 0333 if you need this service. We will have to get you an exact cost based upon your order and geographic destination. Please be advised there will likely be ‘shipping shock’ as the additional cost is typically minimum 35 dollars. Larger orders can cost 75 or more additional dollars for Next Day Air.

Budgetary Considerations.

One of the ‘nice’ things about Growafrogs is that they are ‘affordable.’ When you consider all of the expenses associated with most any other project, the expenses for Growafrogs are low indeed. All Growafrog kits include everything you’ll need to grow the tads (except water) so there are no ‘hidden costs.’ Of course, the frogs need to eat – and Stage Two Food is priced very inexpensively. The ‘Buy 2 Get One Free Special’ lasts a good long time. A larger habitat may be necessary as the frogs grow… and most K-12 institutions have an aquarium or larger habitat ‘on hand’ purchased years ago.

The true cost is pennies a day, the desire to learn about biology and life science, and a little love.

Category: Classroom

They Need To Read.

See thru tadpoles can encourage reading!

Place a Growafrog see thru tadpole kit on a table and surround it with topical books about tadpoles, frogs, amphibians and metamorphosis.

It is our experience that see thru tadpoles will stimulate students to become ‘frequent library visitors.’ In all likelyhood, your pupils will browse a book or two and immerse themselves in words about the vital life processes unfolding in your book repository.

Category: Classroom

Student Interest.

Any educator knows that K-6 students learn more when they are ‘engaged’ in an activity.

As you can literally see thru a Grow-a-frog tadpole’s skin and watch a live heartbeat, we can tell you from now 35 years of experience that your students will become ‘almost immediately engaged’ in this project.

Students are simply attracted to tadpoles! Every student should have the opportunity to see a tadpole change into a frog while they are still in school! We have been told that Growafrogs ‘bring light to childrens’ eyes who are otherwise uninterested in learning.’

Although the morph may take a few weeks, growth may be observed almost daily. Kids look forward to coming to class to watch how much their tadpole has changed since the previous day.

Grow-a-frogs are extremely easy to care for in classrooms, and students love to ‘take turns’ feeding their frogs and doing weekly partial water changes.

Biology is defined as the “scientific study of life.” We humbly submit that there is no book, CD, YouTube video, Instagram picture or film which is better suited for studying life than the study of life itself. Grow-a-frog tadpoles and frogs are a remarkable way to study and appreciate life in your classroom! The scientific ‘hands – on’ metamorphosis observation of see-thru tadpoles to aquatic frogs will certainly stimulate the minds of your future scientists, doctors, veterinarians and ecologists as well as the fertile minds of all of your students including artists, musicians, and poets alike ! Life is important!

Over the course of time as students inevitably return to visit teachers from earlier grades, they are incredulous to learn that a frog they grew years ago when they were in the very same classroom is still alive and well all that time!

Morph Time!

Grow-a-frog tadpoles morph in 3-6 weeks on average.

This can and does vary a bit from tadpole to tadpole. Also, temperature affects the morph time.. In general, tads morph weeks faster at 72 than they do at 66 degrees.

If your curriculum has ‘time’ we highly recommend any one of our Grow-a-frog Kits. However, if the school year is coming to an end or if you simply need to complete the lesson in one class period AND watch the tads grow – then we recommend either the Life Cycle Kit, Morphin Tube Town, or the Super Deluxe Kit. All of these include more than one stage of development.

Tell A Colleague!

In a continued effort to keep our prices as low as possible, we depend upon ‘word of mouth’ advertising far more than media advertising for Grow-a-frogs.

If your students have gained knowlege and appreciation for nature by observing Grow-a-frogs in classroom we would appreciate it you could pass this along to a colleague. Although shipping costs have ‘rocketed’ in the past years, we still are making every effort to provide Grow-a-frogs for our wonderful teachers and students with little or no price increase.

By the way, we understand all too well how schools have been ‘hit hard’ with budget cuts and shortfalls. All too often educators use their own out of pocket money for school projects. With this reality in mind, we try to offer Growafrogs as a ‘cost effective’ lesson for your students. Our Growafrog kits are ‘complete’ and available in a wide selection of low to moderately priced offerings. Refill kits are available, too.

Morph’in Kits.


We proudly offer Growafrog Kits in advanced stages of metamorphosis! Your students may observe tadpole to froglet development in one class period.

We invite you to consider our Life Cycle Kit or Morph’in Tube Towns. Our Life Cycle Kit includes juvenille, back limb, front limb, ‘metamorphic climax’ and froglet stages of development. The Morph’in Tube Towns include a back limb tadpole and a front limb tadpole. Also, our Super Delux Kit includes a tadpole and a young froglet just post metamorphosis.

School Address Preferred.

We prefer to address your order to a school as ‘someone will be there’ to accept the package and it will not get left outdoors or in a mailbox.

Of course, there are exceptions. If you are planning to receive your Grow-a-frog during school break or Saturday then obviously address it elsewhere such as a work address, business address, or at least an address ‘where someone will be home.’ If you need to use an address where someone will not be home, please pay extra special attention to tracking information so that you may anticipate arrival. Also, itis helpful to provide an email address AND a text enabled phone number so that tracking information can be emailed and in some instances texted directly to you if the package will be delivered directly to the Post Office for pickup.

Staged Tadpole / Frog Kits For Education.

We recognize that lesson plans need to be completed ‘on time’ and offer our Life Cycle Kit and Morph’in Tube Town Kits – which include tadpoles in advanced stages of development and newly morphed froglets.

This allows your students to see much of the morph in one class period, not weeks. Having said that, there is no substitute for direct observation of the entire tadpole to frog metamorphsis. We highly encourage you to allow your students to take the time to observe the ‘miracle of metamorphosis’ and grow the tads into frogs!

Category: Live Tadpoles

Larger Frog Habitat.

Certainly. When the time eventually comes for a larger habitat ‘you’ll know’ as your frog will seem like it needs a more spacious home. Tadventures, Tadpole Single Tube Town, and Tadpole Double Tube Town are designed for tadpoles and young froglets. The Tube Town Kits are especially useful as they include Tube Caps – which allow you to grow tadpoles and froglets in the same habitat. Tube Caps are also useful in separating smaller froglets from larger froglets because Growafrogs need to be compatible in size or they could actually EAT each other. If you have a Tadventure Kit we suggest that you separate the froglet from the tadpoles as soon as they morph.

As your froglets grow and become more compatible in size with each other we highly recommend that you place them into a larger habitat. An ordinary ten gallon aquarium (or larger) makes an excellent home for Growafrogs. Many people have a ‘spare aquarium’ at home and these make wonderful Growafrog habitats. We offer Grow-a-frog Shade Domes that fit any standard 10 gallon aquarium. You may easily ‘retrofit’ your 10 gallon tank to a Growafrog home by adding Shade Domes. Our Shade Domes provide cover so that your Grow-a-frog cannot get ‘loose’ as it jumps during low pressure atmospheric events such as thunderstorms. These beautiful Shade domes also keep your Growafrogs feeling ‘protected’ as your semi-nocturnal Growafrog prefers shade to direct light.

We also offer our beautiful kids-safe Plexiglass BIG ‘n Hoppy and Tube City Habitats available in several vivid colors for your older frogs.

Category: Live Tadpoles

Froglet Habitat.

We offer several larger frog habitats including our Stage Two Single Tube Town, Stage Two Double Tube Town, BIG ‘n Hoppy and Tube City Habitats. If you are considering getting your frog a freind these are great options as all Tube Towns include a free frog friend at no addtional cost at all (By the way.. if you do NOT want to receive the frog friend simply write NO friend in the ‘Special instructions or Comments’ box which appears at the ecd of the online ordering process – or call 352 544 0333 to order. Also, an ordinary 10 gallon (or larger) aquarium makes an excellent habitat for Growafrogs. Many people have a ‘spare’ aquarium at home and if you happen to have one this is an excellent and inexpensive habitat. If you choose to use an aquarium we recommend that you keep it for Growafrogs only, no fish (a snail is OK). We suggest that you consider using Growafrog Shade Domes as a cover for all 10 gallon tanks as shade keeps your Growafrogs feeling safe and secure… and also to use Habitat Soil and perhaps our little Growafrog filter, too.

Transferring To Stage Two.
We highly recommend that you order Stage Two Food shortly after the front arms emerge. Metamorphosis hastens after the tadpole shtops feeding Stage One Tadpole Food and this will leave enough time for delivery.
Growafrog Kits now include a LARGER habitat so that you do NOT have to transfer your tadpole to a larger habitat after the front arms emerge. If you are familiar with Growafrog Kits from years gone by this is a significant ‘upgrade’ and makes your tadpoles’s morph ‘seamless.’
Whether you call the Gilly Hotline at 352 544 0333, order online, via fax or Postal Service – we always ship all Stage Two orders promptly.

Category: Live Tadpoles

Growafrog’s First Stage Two Food Nugget.

Please feed one Stage Two Food nugget in the morning, and one in the evening, when ‘the tail is almost gone and your Growafrog looks very much like a frog.

Please be alert for feeding as the morph happens quickly at this stage. You will be able to see daily changes. Do NOT wait until the tail is completely gone. Feed Stage Two Food when the tail is about 1/8 to 1/4 inch long. We also recommend a 1/4 partial water change with spring water after your froglets first feeding (wait about 15 minutes or so). This will help to keep the water clean even if your frog does not eat the first time you feed it.

Category: Live Tadpoles

Refresh The Habitat.

Change up to 90 percent of the water. Also change a portion of the water (1/4 to 1/2) more frequently… Even daily if necessary. There are many factors which affect the rate at which your tadpole morphs. Temperature and genetics are certainly important factors. Usually though your tadpole is sensing ‘dry’ and not ‘rainy’ conditions. Accumulation of waste in the habitat can easily be removed by changing 90 percent of the water. It may help to ‘stir up the bottom with a disposable drinking straw to dislodge waste particles as you change the water.

Category: Live Tadpoles

Tail Absorption.

Your tadpole is undergoing dramatic changes during metamorphosis. Your Growafrog’s digestive tract is changing, too… as the filter feeding tadpole becomes a ‘solid food’ eating frog. During metamorphosis, when it is neither tadpole nor frog, your Growafrog does not eat. It gets all the nutrition it needs by using enzymes to decompose the tail…which it uses as a source of energy or ‘food.’

Category: Live Tadpoles

Metamorphosis Rate.

The average time that it takes to complete the morph is about five weeks. The morph begins when the back legs emerge, and ends when the tad becomes a frog. Many factors influence growth rate, but the major ones are temperature and genetics. At lower temperatures, (below 68 degrees) metamorphosis may 2 months or more. There seem to be some tads that are ‘genetically programmed’ to morph fast. Some grow quickly at even lower temperatures.

Category: Live Tadpoles

Growth rate variance.

Like people, some Growafrogs grow faster than others. There are ‘fast morph’ers’ and ‘slow morph’ers.’ Growth rate has nothing to do with the health of your tadpole… it just takes longer for them to change. It is not at all unusual for one to completely morph, and another to have hardly grown front limbs.

Category: Live Tadpoles

Dietary Change.

During metamorphosis there is a period of time when your Growafrog does not eat at all. All of it’s nutritional requirements comes from the re-absorption of the tail, which provides the necessary nutrition for the morph. Remarkable, indeed.

Stop feeding your tadpole Stage One Tadpole Food after the front arms emerge. Do not feed at all from the time the front arms emerge until the tail is just 1/4 inch long. Start feeding your froglet Stage Two Frog Food after the tail is almost gone and your Growafrog is a very small frog with a short 1/4 tail. Continue to feed Stage Two Frog Food after the tail is completely gone. Please remember to do a 1/4 water change with Spring Water weekly during metamorphosis, too. Partial water changes are very important.

Category: Live Tadpoles

Grow-a-Frogs should remain at the same temperature during metamorphosis as during other stages…. around 68 – 72 degrees or ‘normal home temperature.’ Please do NOT place a thermometer in the habitat and measure it 3 times a day (unless you are doing some kind of observation or experiment). It is absolutely not necessary. Your tadpole will adjust to any fluctuations.

Temperature tends to affect the rate of metamorphosis. Your tadpole will morph faster at 72 degrees. We highly recommend that you do NOT use ‘aquarium heaters.’ Your frog is a frog NOT a fish and the morphing tadpoles and frogs tend to swim near snd sometimes touch the heaters. This is harmful as your morphing tadpoles and post morph frog can burn themselves on the heater elements in much the same way that you could burn yourself on a stove.

If you wish to ‘speed up’ the morph by increasing the temperature in winter… our suggestion is to keep your tadpole’s habitat ‘in the zone’ of a heater. Keep your tadpole’s habitat within the normal range of a space heater , radiator or heat vent. Do NOT place your tadpole’s habitat ON any heater…ever. The temperature will get far too hot. If the area of the heat source feels ‘comfortable’ to you then it is ‘comfortable’ for your tadpole and it will hasten metamorphosis.

Category: Live Tadpoles

Aquatic Habitat.

Grow-a-Frogs are not common frogs, so they do not behave in ordinary ways. Normally, metamorphosis is the time when frogs ‘hop out of water and onto land.’ They live a marshy existence, and go back to the water to mate and lay eggs. Grow-a-Frogs never leave the water, so they do not need to or ‘want’ to go on land. Indeed, if they do leave the water, they could not survive very long unless they remain very, very moist.

Category: Live Tadpoles

Metamorphosis is a time of dramatic change. Tadpoles move around and ‘swim’ using their tail as a ‘propeller.’ During metamorphosis, they grow legs and arms, then lose their tail completely. Growafrog tadpoles have ‘tentacles’ that allow them to sense food, foreign objects and movements in the water. Growafrog frogs have something called ‘lateral lines’ that accomplish much the same thing. They look a lot like ‘stitching’ in the back of your frog…kind of like someone took a needle and thread and sewed it together.

Growafrog Tadpoles breathe with gills and lungs. Growafrog Frogs do not have gills. They breathe air with their lungs… just as you do when you are in a swimming pool. Growafrog tadpoles are ‘filter feeders.’ They eat all the time by filtering suspended food particles from the water. Growafrog frogs are ‘meal time eaters.’ They eat or snack only when they are hungry…kind of like you!

Category: Live Tadpoles

Gills and Lungs.

Your Grow-a-Frog tadpole is quite unique. Ordinary tadpoles have gills. During the tadpole stage they ‘breathe’ like a fish, by passing oxygenated water through their gills and absorbing the oxygen. Frogs, of course, have lungs and breathe air… just like you do. Grow-a-Frog tadpoles, on the other hand, have both gills and lungs in the tadpole stage. This is why you see your tadpole come to the surface and ‘take a gulp of air.’ This is truly a remarkable adaptation to it’s environment.

Category: Live Tadpoles

Live Heartbeat.

Growafrog tadpoles have transparent or ‘see-thru skin.’ Almost miraculously, you can see your tadpole’s live heart beat!! If you look very closely, you can actually see the blood being pumped thru the heart.

Just pick up the tadpole’s habitat and hold it above your eyes… so you are now looking at the ‘bottom’ of the tadpole. The easily seen large, silver colored structure is the gut. Look towards the mouth, and you will see a smaller, but still easily visible gold colored object – your tadpole’s heart. You can see the blood being pumped through the heart with you naked eye… although it is so fascinating you may want to use a magnifying glass for a closer look.

Category: Live Tadpoles

Stage One Food Formula.

Stage One Tadpole Food is made of two parts – one of which does not dissolve. The portion of Stage One Food which dissolves provides immediate food for your tadpole. The undissolved portion is a growth media for microscopic, live food.

If you observe that your tadpole does not eat all of the Stage One Food, you are correct. Stage One Food is designed so that only the portion which dissolves is actually ‘eaten’ by your tadpole.

Category: Live Tadpoles

Excess Poop !

Change a portion of the water. A little cloudiness in the water is benficial and necessary for your tadpole to survive. Having said that, if there is lots of ‘poop’ on the bottom of the habitat go ahead and do a partial water change. You may need to empty 1/2 or even 3/4 of the water and refill with well or spring water. If the habitat is especially dirty ‘then pour out some more of the dirty water and refill again’.

Category: Live Tadpoles


Add a little water – daily if necessary. You might be ‘surprised’ at how much water evaporates daily. Adding just small amounts of water will refresh the ecosystem and keep your tadpole morphing!

Category: Live Tadpoles

Habitat Color.

The color of the water in your tadpole’s habitat is approximately the color of lake water. Most of the time it stays a light brown color.  Any greenish growth comes from algae, which is a plant and therefore needs light to grow. If your tadpole’s habitat receives some ambient light it will turn a bit more greenish.

Category: Live Tadpoles

Stage One Food Formula.

Stage One Tadpole Food is made of two parts – one of which does not dissolve. The portion of Stage One Food which dissolves provides immediate food for your tadpole. The undissolved portion is a growth media for microscopic, live food.

If you observe that your tadpole does not eat all of the Stage One Food, you are correct. Stage One Food is designed so that only the portion which dissolves is actually ‘eaten’ by your tadpole.

Environmental Cues.

Your tadpole responds to environmental cues such as the beginning of ‘rainy season.’

You can mimic the onset of rainy season in your home by adding even a small amount of water daily to compensate for the effects of evaporation and ‘trick’ your tadpole into sensing ‘rain.’

This is very easy to do. Just pour in spring water.

Your remarkable Growafrog tadpole has the ability to survive in dry or rainy weather. In dry weather it stays a tadpole far, far longer. This built in survival mechanism allows your tadpole to survive as a tadpole in dry weather and hastens metamorphosis to the aquatic frog stage when ponds are filling up with water.

Grow-a-Frog Eco-system.

Your tadpole feeds by filtering the water it lives in. It does not eat ‘meals’ such as your frog (and you). It eats all the time. Every time your Growafrog tadpole opens it’s mouth, it is filtering dissolved microscopic particles out of the water. This is why it is so important to establish the tadpole Eco-system. Stage One tadpole food is made of two parts. One part dissolves instantly ‘for immediate consumption.’ The other part (the one that sinks) in combination with Nutri Sand forms a growth media for live food! This way you can feed your tadpole once a day but food is growing (and your tadpole is eating) 24/7…

Daily Feeding.

Feed your tadpole one level spoon of food per day. It is important to feed daily, especially when you first receive your tadpole, to insure that the eco-system becomes established. After about 2 weeks, however, do not become too upset if you miss a day. The eco-system has established and there is enough food for your tadpole even if you miss a day.

You can help your tadpole by… believe it or not… observing it’s ‘poop.’ Growafrog tadpoles are always eating and therefore always ‘pooping’ ( OK, almost always ). If the water looks very clean and you do not see any ‘poop’ in the vent directly between your tadpole’s back legs… then go ahead and add an extra spoon or two of Stage One Food to refresh the ecosystem.

Poop is good!

Spring water labels can be confusing. There are many locally distributed inexpensive spring water brands available, usually in gallon containers. These are all just fine for your tadpole and usually cost less than .99 a gallon. Please look for the name of the spring ‘origin’ on the label. Usually it says something like Source – Bear Mountain Springs, Uphigh Pennsylvania….or something to that effect. Do not use ‘purified’ water…. this is just tap water that has gone through a purification system (usually reverse osmosis). Spring Water is a much better alternative for your tadpole. By the way, if you happen to have well water or live near a real spring, lake, or river… that water will do fine.

Your froget’s first meal is very important. Please feed one Stage Two Nugget when your Growafrog looks like a frog WITH a tail. Morphing Growafrogs eat Stage Two Food when the tail is ‘almost gone’ and about 1/4 inch long, so please feed before the morph is totally complete. Even if you do not observe your froglet eating, place one nugget in the habitat in the morning – and one nugget in the evening. Change 1/4 of the water with bottled spring water…every other day if you can…until the morph is over. Please do not use Water Crystals… yet.

Make sure that your frog is eating and the morph is complete before using Water Crystals. If you have a Stage Two Habitat, it is OK to move your tadpole/froglet in there at any time. You do not have to wait for the morph to complete before moving to Stage Two. Just please remember to use Spring Water.. even in the Stage Two Habitat.. if you have a tadpole and/or froglet that has not quite completed the morph.

We do realize that you need to receive your order ASAP. Unless otherwise specified we ship all orders ASAP, weather permitting.

We send a TRACKING EMAILwhen your order leaves our facility and is on it’s way to you. If you do not receive a tracking email CHECK YOUR SPAM FOLDER.

We highly recommend that you track your delivery especially if you are anticipating a live tadpole or froglet!

By the way if you have any questions about delivery please DO NOT HESITATE to call the Gilly Hotline at 352.544.0333 daytime Eastern Time or email. It is VERY important for us to communicate and coordinate delivery with you!

We are able to ship most of the school year. We are very sorry but there does come a time when it is simply too hot or cold to ship. Most of the time ( not always, of course ) extreme heat 95 + degrees coincides with summer vacation. Also, we prefer not to ship if the temperatures are below 25 degrees as even with insulation of course water will freeze if the package is left outdoors. You can definitely help us by providing a school, work, business or ‘address where someone will be home’ so that the package does not stay outside or in a mailbox overnight.

Use bottled spring water or well water to grow tadpoles. NEVER use tap water. Make sure the ‘source’ of the spring appears on the bottled spring water. Fill the Habitat with water. Feed one spoon of Stage One Food every day. Change 1/2 of the water once a week. STOP feeding Stage One Food when the front arms emerge. START feeding Stage TWO Food when your tadpole has about a 1/4 inch tail and looks very much like a frog.
