African dwarf frogs are fully aquatic amphibians that breathe air at the surface. Their small size does not make them suitable for an unfiltered bowl: they need stable, clean water, an escape-proof aquarium and deliberate feeding.
This guide covers Hymenochirus species. For a first setup, choose a quiet, species-only aquarium where you can check that every frog eats. They are interesting animals to observe, rather than pets to handle.
African dwarf frog care at a glance
| Requirement | Practical starting point |
|---|---|
| Aquarium | 10 gallons or larger for a pair; choose a larger, wide tank for a bigger group |
| Temperature | A stable 76–78°F |
| Water quality | 0 ppm ammonia and nitrite; keep nitrate low, ideally below 20 ppm |
| pH | Approximately 6.5–7.5; avoid sudden changes |
| Equipment | Cycled gentle filter, thermometer, heater as needed and secure ventilated lid |
| Food | Small sinking aquatic-frog foods and varied, appropriately sized meaty foods |
| Commitment | Several years of daily observation and regular maintenance |
These are planning guidelines, not a stocking formula. Confirm the conditions your frogs are accustomed to before bringing them home. Flip Aquatics’ frog care guide provides additional species-specific water and feeding guidance.
Check that you are buying the right frog
African dwarf frogs and African clawed frogs are different animals. Dwarf frogs have webbing on all four feet; African clawed frogs have unwebbed front feet and grow much larger. Ask the seller to identify the species rather than relying on its size as a juvenile.
The OATA aquatic amphibian care sheet explains this distinction and recommends a broad aquarium footprint, gentle filtration and unobstructed access to air.
Set up an aquarium they can navigate easily
Choose a long, relatively shallow tank rather than a tall display. Leave a clear route to the surface and provide sturdy plants or smooth resting places near it. Frogs should not have to struggle through dense floating plants or a strong filter current to breathe.
A secure lid must cover gaps around equipment while allowing ventilation. Leave air above the water. These frogs do not need a dry land area, and an open aquarium creates an escape risk.
Use smooth decorations without sharp edges or narrow traps. A bare bottom makes feeding and waste removal easy; if using substrate, avoid loose pieces small enough to swallow. Provide several shaded hiding places so one frog cannot monopolize the only shelter. Keep lighting on a regular day/night schedule.
Cycle the aquarium before adding frogs. A gentle sponge filter is one option; protect other filter intakes from small limbs. Check temperature with a separate thermometer and use an appropriately sized aquarium heater if the room cannot maintain it. Petco’s care sheet also covers enclosure security and equipment.
Feed every frog, not just the aquarium
Offer a small daily meal and watch each animal eat. Place food close enough for it to find, using a feeding dish or a clean aquarium feeding pipette if helpful. Do not squirt food into its mouth or force-feed with tweezers.
Choose sinking foods formulated for aquatic frogs, with particles that fit their small mouths, and vary the diet with suitable thawed frozen invertebrates such as brine shrimp or daphnia. For example, Zoo Med’s aquatic frog food is a sinking micro-pellet formulation; this is an example of the food type, not a claim of personal testing.
A frog may not immediately recognize pellets as food. Offer familiar foods while gradually introducing alternatives, and confirm swallowing rather than assuming missing food was eaten. Remove leftovers after the feeding session. Adjust portions to body condition and waste rather than repeatedly adding food for a fixed number of minutes. Fish flakes, algae and occasional scraps do not constitute a reliable frog diet.
Aquarium Co-Op’s feeding guidance highlights their difficulty competing with faster fish. A frog that consistently misses meals needs a change in feeding arrangements.
Tank mates: a dedicated frog tank is easier
Keep similarly sized frogs together with enough space and shelters. A species-only setup makes it easier to monitor appetite and prevent harassment. Community fish can steal meals, nip limbs or intimidate frogs; very small animals may be eaten.
Do not assume a betta is compatible simply because both animals are small. If you try a community arrangement, have a fully suitable separate aquarium available and move the animals if feeding or behavior deteriorates.
Maintenance and signs of trouble
Test water at least weekly and whenever behavior changes. Start with a roughly 25% weekly water change, adjusting to test results and waste levels. Treat replacement tap water for chlorine and chloramine, match its temperature, and siphon debris carefully while keeping track of every frog. Our water test kit guide explains what to measure.
Loss of appetite, weight loss, wounds, persistent abnormal floating, swelling or fuzzy growth deserve prompt attention. Check water and temperature immediately and contact a veterinarian experienced with amphibians. Do not diagnose a disease from appearance alone or add fish medication, copper treatments or salt without species-appropriate professional advice.
Handling, hygiene and breeding
Avoid routine handling. When relocation is necessary, guide the frog into a suitable container of aquarium water without trapping its limbs. Keep it submerged and secure during the move.
The CDC warns that healthy-looking amphibians and their tank water can carry Salmonella. Wash hands with soap after contact with the tank or supplies. Keep equipment away from food preparation areas. Young children and people at higher risk of serious infection need particular precautions; these are not hands-on children’s pets.
Breeding and raising tadpoles require separate planning, suitable tiny foods and protection from adult predation. Do not deliberately neglect water changes or create unstable conditions to stimulate breeding. Establish healthy adult care before attempting it.
