Best Tank Mates for African Dwarf Frog: Compatible Fish and Species to Avoid
The best tank mates for African dwarf frogs are small, peaceful fish that stay in the middle and upper water, such as rasboras, neon tetras, guppies, honey gouramis and cherry barbs, along with nerite or mystery snails. Avoid anything that can swallow, nip or grab a frog. Just as important, plan how the frogs will get fed, because in community tanks these slow, near-blind eaters are far more likely to lose out at mealtime than to be attacked.
Why Tank Mate Choice Is Different for African Dwarf Frogs
African dwarf frogs (ADFs, genus Hymenochirus) are fully aquatic, peaceful bottom-dwellers that reach about 1.5–2.5 inches (4–6 cm). Several traits shape which fish can share their tank:
- Poor eyesight. They find food by smell and by feeling vibrations, not by sight.
- Slow eating. A school of tetras can clear a tank of food before a frog has found its first bloodworm.
- Lunging at movement. Frogs snap at anything that wiggles nearby, including long fins and baby shrimp.
- Weak swimming. They have to swim up for air, so strong currents and deep tanks tire them out.
- Delicate skin. Any wound from nipping can let in a serious fungal or bacterial infection.
So you are looking for fish that are peaceful, roughly 1–3 inches (2.5–7.5 cm) long, too big for a frog to swallow and too small or gentle to hurt one. Fish that live in the middle and top of the tank are ideal because they leave the bottom to the frogs.
Shared Water Parameters and Tank Setup
Pick tank mates that are comfortable in the same water:
| Parameter | Target for an ADF community |
|---|---|
| Temperature | 72–82°F (22–28°C); hold 76–78°F (24–26°C) |
| pH | 6.5–7.5 |
| Hardness | Soft to moderately hard, roughly 5–20 dGH |
| Ammonia / nitrite | 0 ppm |
| Nitrate | Under 20 ppm |
| Water depth | 16 inches (40 cm) or less |
| Flow | Gentle; a sponge filter or baffled outflow |
Temperature advice varies: some care sheets give the full 72–82°F range, while others quote narrower windows. Cardinal tetras want the warm end, and zebra danios are sometimes listed down to the mid-60s°F. Holding 76–78°F suits the frogs and every fish recommended here. In most US homes that means you need a heater.
Most US tap water falls within the hardness range above, but test yours before stocking fish that prefer soft water.
Setup essentials:
- A tight-fitting lid. An escaped frog can dry out within minutes.
- Smooth sand or fine, rounded gravel that won't scrape skin.
- Dense plants and caves so frogs have places to hide and rest.
- A sponge filter or baffled output. Strong flow wears the frogs out, and sponge filters won't suck in small animals.
How Big Should the Tank Be?
Estimates range from 5 gallons for frogs alone, to 10 gallons with a betta, to 20 gallons for a community. We recommend 20 gallons (75 L) or more for any mixed community. A 10 gallon (38 L) tank can house 2–3 frogs plus a small group of nano fish or a single betta. Frogs are messy eaters that produce a fair amount of waste, so count them fully when you work out your stocking, not as "extras."
Keep ADFs in groups of at least 2–3, ideally 3–5. They are more active and confident with company. A common guideline is one frog per 2–5 gallons.
Best Fish Tank Mates for African Dwarf Frogs
- Rasboras (harlequin, lambchop, and chili in planted nano tanks): calm schoolers that stay in the middle of the tank. Keep 6–8 or more.
- Neon and cardinal tetras: schools of 6+. Cardinals want warmer, softer water. Browse tetras on FishyHub.
- Guppies and Endlers: hardy top-dwellers. The frogs will eat any fry.
- Honey gourami: gentle, plant-loving and small. Don't confuse it with larger gourami species.
- Cherry barb: the one barb that is usually peaceful. Keep it in a group.
- Hatchetfish: they stay right at the surface, but they jump, so the lid must be tight.
- Zebra danios: hardy and stay up top, but they are fast and can scare shy frogs away at feeding time.
- Platies and mollies: they get along with frogs but eat greedily.
- Small bottom and algae crew: pygmy or other small corydoras and otocinclus, both in groups.
Where Opinions Split
Bettas. Some keepers call a betta the perfect ADF companion, while others urge caution. The risks are real: frogs may bite long fins, a feisty male can harass frogs, and bettas steal food. A betta can work in 10 gallons or more (ideally 20) if you choose a calm fish, short-finned if possible, target-feed the frogs, and have a backup plan for separating them if it goes wrong. Keep a spare tank or a divider ready, or line up someone who can take one of the animals.
Corydoras. Some sources call them ideal, while others say they crowd the bottom and compete with frogs for food. They are fine in 20 gallons or more if you choose pygmy or small species and target-feed the frogs.
Platies, guppies and danios. All three are peaceful, but they are quick to grab food. Keep them, and simply feed the frogs separately.
Invertebrate Tank Mates
- Nerite and mystery snails: a good cleanup crew. Their trapdoor (operculum) seals them in if a frog gets curious.
- Bamboo (wood) shrimp: too big for frogs to eat. They filter-feed, so they need some current and fine food.
- Amano shrimp: adults are usually fine.
- Cherry shrimp: adults may survive, but small shrimp and shrimplets get eaten. Keep them only in heavily planted tanks, and expect the colony to grow slowly or shrink.
Species to Avoid
- Anything big enough to swallow a frog: oscars, large cichlids, arowanas, big gouramis.
- Fin and skin nippers: tiger barbs and most other barbs, serpae tetras, some dwarf cichlids. A small nip wound on a frog can become a deadly infection.
- Plecos and Chinese algae eaters: they may latch onto a frog's slime coat.
- Goldfish: they need cooler water and grow large and messy.
- Crayfish, crabs and large prawns: their claws will grab frogs.
- Turtles: they will treat frogs as food.
- African clawed frogs: they grow large and eat ADFs.

Target Feeding, Step by Step
The feeding routine decides whether frogs thrive in a community tank.
- Feed the fish first. Scatter floating flakes at the surface so the fish are busy up top.
- Then feed the frogs. Drop sinking food, such as frozen bloodworms, brine shrimp, mysis or frog pellets, right in front of each frog using long tweezers or a turkey baster.
- Use a feeding station. A shallow dish on the substrate keeps food in one spot where frogs learn to look for it.
- Feed at dusk. ADFs are most active after the lights dim, when fish are also settling down.
- Watch every frog eat. Count frogs and make sure each one gets food.
- Remove leftovers after a short while to protect water quality.
Feed frogs 3–4 times a week, although some owners prefer small daily portions. You can find frozen and sinking foods under food and supplements.
Spotting a starving frog early: watch for a thinner body, a belly that looks sunken rather than rounded, and a frog that is always searching the substrate. Start target feeding right away at the first sign.
African Dwarf Frog vs. African Clawed Frog
Clawed frogs are sometimes sold mislabeled as dwarf frogs, especially as juveniles. Check before buying:
| Trait | African dwarf frog | African clawed frog |
|---|---|---|
| Front feet | Webbed | Unwebbed, no webbing between fingers |
| Snout | Pointed | Flat, rounded |
| Eyes | On the sides of the head | On top of the head |
| Adult size | About 1.5–2.5 in (4–6 cm) | Much larger; grows well past ADF size |
| Behavior with fish | Peaceful | Predatory; eats small fish and ADFs |
Quarantine and Buying Healthy Frogs
- Cycle the tank first. Add frogs only to a mature, stable tank.
- Quarantine new fish and frogs for 2–4 weeks. ADFs are vulnerable to chytrid fungus and bacterial infections, and a new fish can bring in disease.
- Buy from a healthy source. Look for active frogs with rounded bellies, clean skin and no white fuzz or redness, kept in clean tanks.
Common Mistakes and Troubleshooting
- Thin frogs, sunken bellies: they are starving. Switch to target feeding with a dish.
- Fish with shredded fins: frogs are mistaking fins for food. Separate the feeding zones and avoid long-finned fish.
- White fuzzy patches or red skin: likely a fungal or bacterial infection, often after nipping or poor water. Test the water, then quarantine and treat.
- Frogs vanishing: check for gaps in the lid, and ask whether any fish is big enough to eat a frog.
- Shrimp colony shrinking: the frogs are eating shrimplets.
- Exhausted frogs: strong filter output. Baffle it or switch to a sponge filter.
- Unusually fast-growing "dwarf" frogs: they may be clawed frogs. Separate them right away.
- Frog floating motionless: usually normal. ADFs rest at the surface in a relaxed "zen" pose.
If a pairing fails, move the problem fish or the frogs to a spare tank, use a divider for the short term, or rehome the animal with another keeper or a local fish club. Never release it outdoors.
Frequently Asked Questions
Can African dwarf frogs live with bettas?
Yes, with caveats. Use at least 10 gallons (ideally 20), pick a calm, preferably short-finned betta, and target-feed the frogs so the betta can't steal their food. Watch for fin biting or harassment, and be ready to separate them.
Will African dwarf frogs eat my fish?
They will eat fish fry and tiny shrimp, but adult fish of a suitable size are safe. Frogs may nip at long, trailing fins during feeding by mistake, which is another reason to choose short-finned species.
Can African dwarf frogs live with goldfish?
No. Goldfish prefer cooler water than tropical frogs need, and they grow large and produce a lot of waste. Keep the two in separate tanks.
How many African dwarf frogs should I keep?
Keep at least 2–3, ideally 3–5. A common guide is one frog per 2–5 gallons, and in a mixed community, count the frogs' waste when you plan your stocking.
Are snails and shrimp safe with African dwarf frogs?
Nerite and mystery snails, Amano shrimp and bamboo shrimp are generally safe. Dwarf shrimp such as cherry shrimp risk losing their babies and small juveniles, so keep them only in heavily planted tanks.
How do I make sure my frog is eating?
Feed the fish first, then place sinking food in front of each frog with tweezers or a baster, or in a feeding dish. Feeding after the lights dim helps, and watching each frog take food is the only way to know it is eating.
Build a Frog-Friendly Community
African dwarf frogs do well with peaceful mid- and top-water fish, a gentle filter, a warm and stable tank, and a feeding routine that gets food to them first. When you are ready to stock your tank, browse compatible fish, snails and shrimp in FishyHub's freshwater livestock collection.
