This guide covers how to tell the two apart, the water parameters and setup they need, who they can live with, and how to feed them properly.
First: Dwarf Frog or Clawed Frog?
Before anything else, know which frog you have — it changes everything about the tank.
African Dwarf Frog (ADF). Stays small, around 1.5 inches, peaceful, and spends its life in open water darting to the surface for air. Its front feet are fully webbed. ADFs are community-safe with the right tank mates and live about 5 years.
African Clawed Frog (ACF). Grows to 4–5 inches or more, is a committed predator that will eat any fish or shrimp it can fit in its mouth, and has clawed, unwebbed front toes. ACFs are hardy and can live 15+ years, but they are a species-only animal — keep them alone or with another clawed frog of the same size, never in a community tank.
The tell is the front feet: webbed = dwarf, clawed = clawed frog. Stores mislabel these constantly, so check before you buy.
The Essentials: Warm, Cycled, and Covered
Aquatic frogs are tropical. Both species want water around 72–78°F (22–26°C), so unlike an axolotl they do use a heater. Stable warmth keeps their appetite and immune system healthy.
Your tank must be fully cycled. A frog's permeable skin makes it very sensitive to nitrogenous waste, so your tank needs an established nitrogen cycle with ammonia at 0 ppm and nitrite at 0 ppm before a frog moves in. A fishless cycle takes several weeks — start it ahead of time.
Always keep a lid on. Both ADFs and ACFs will escape a tank without a cover. And because they are air-breathers, don't make the water so deep that the frog struggles to reach the surface.
A solid aquatic frog water parameters target looks like:
- Temperature: 72–78°F (22–26°C)
- Ammonia: 0 ppm
- Nitrite: 0 ppm
- Nitrate: under ~30 ppm — keep it down with regular partial water changes
- pH: roughly 6.5–7.8 (stable matters more than a specific number)
- Flow: gentle — both species are weak swimmers
A few more setup fundamentals:
- Tank size: about 5–10 gallons works for a small group of dwarf frogs; an African Clawed Frog needs 20+ gallons on its own because it is large and messy.
- Substrate: use smooth sand or stones too large to swallow. Like axolotls, frogs can ingest small gravel and suffer impaction, so bare-bottom or soft sand is the safe call.
- Gentle flow: baffle a strong filter output. Dwarf frogs in particular get worn out by heavy current.
- Hides and plants: caves, driftwood, and live or silk plants give frogs security and resting spots near the surface.
How TankMate Helps Frog Keepers
Aquatic frogs are easy to get wrong in two ways: housing a predatory clawed frog with fish, and letting a slow dwarf frog quietly starve in a community tank. TankMate is built to catch both.
TankMate is an AI-powered aquarium app for iOS and Android that supports aquatic frogs in freshwater and planted tanks. Add a frog to your inventory and its compatibility engine applies frog-specific rules: it warns that an African Clawed Frog will prey on tank mates and should be kept species-only, and that an African Dwarf Frog loses the food race to quick fish and needs target feeding. Log your water and TankMate scores it 0 to 100 against tropical, frog-appropriate parameters so you catch drift before your frog shows stress.
Not sure whether the "dwarf frog" you bought is actually a clawed frog? AI species identification reads a photo and tells you which one you're really looking at — exactly the store mislabel this hobby is famous for. And AI photo diagnosis gives you an informed starting point if something looks off, like bloating, redness on the legs, or fungus.
One honest note: an app is a husbandry tool, not a vet. If your frog shows signs of real illness — bloating, red or raw skin, refusing food, or lethargy — please consult an exotic or aquatic veterinarian.
Sourcing Your Aquatic Frog Supplies
A good frog setup needs a reliable heater and thermometer, a gentle, baffled filter, safe sand or smooth substrate, a secure lid, and quality frog food like sinking carnivore pellets, frozen bloodworms, and brine shrimp.
TankMate can point you toward a recommended local partner store for this kind of gear, with nearby vendors as a fallback when there's no preferred partner in your area. A shop that actually keeps frogs can also help you confirm you're buying a dwarf frog, not a clawed one.
Aquatic Frog Care FAQ
What's the difference between an African Dwarf Frog and an African Clawed Frog?
Size and temperament. A dwarf frog stays tiny (about 1.5 inches), is peaceful, and has fully webbed front feet. A clawed frog grows to 4–5 inches or more, is a predator that eats anything it can fit in its mouth, and has clawed, unwebbed front toes. Check the front feet before you buy — stores mislabel them often.
Can African Dwarf Frogs live with fish?
Yes, with calm, warm-water community fish. Avoid fin-nippers and large or aggressive fish, and make sure the frog actually gets fed, since it's slow and near-sighted. Never house a dwarf frog with a clawed frog.
Do aquatic frogs need a land area?
No. Both species are fully aquatic, but they breathe air and must reach the surface, so don't make the water too deep — and always use a lid, because they escape.
What do aquatic frogs eat?
They're carnivores: sinking frog or carnivore pellets, frozen bloodworms, and brine shrimp. Target-feed dwarf frogs so faster fish don't take all the food.
How warm should an aquatic frog tank be?
Tropical, roughly 72–78°F, fully cycled with ammonia and nitrite at 0 ppm.
Ready to Set Up Your Frog Tank the Right Way?
Aquatic frogs reward keepers who match the frog to the tank and keep the water warm and clean. TankMate helps you do exactly that, with frog-aware compatibility warnings, species ID to settle the dwarf-versus-clawed question, a clear Tank Health Score, and AI photo diagnosis.
TankMate is free to download on iOS and Android, with an optional Pro upgrade when you want more. Set up your frog tank in the app and give your little swimmer a stable, well-matched home.
