Part of the Dwarf Frogs
Small, fully aquatic frogs kept in heated, filtered freshwater aquariums. Peaceful and beginner-friendly, they live entirely underwater and are observed rather than handled.

Habitat & space requirements
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Habitat & enclosure
African dwarf frogs are fully aquatic and never leave the water, so they are kept in a filtered, heated aquarium rather than a terrarium. Provide at least 5 gallons (about 19 liters) for a small group of two or three, with a few extra gallons per additional frog; a tight-fitting lid is essential because they will occasionally try to climb or jump out. Use fine sand or smooth, large gravel that cannot be swallowed, gentle filtration (these weak swimmers dislike strong currents), and plenty of live or silk plants, caves, and low decor so they can rest near the surface to breathe air.
Keep water warm at roughly 75-82 F (24-28 C) with a reliable aquarium heater, a near-neutral pH around 6.5-7.8, and zero ammonia and nitrite through a fully cycled tank and regular partial water changes. Always dechlorinate tap water, since chlorine and chloramine are harmful to their permeable skin. Low, diffuse lighting suits them best.
Substrate
Use smooth, larger river stones or sand rather than small gravel, which these frogs can accidentally swallow and become impacted. Sand is often safest since anything small enough to fit in their mouth poses an ingestion risk.
Equipment & setup
A fully aquatic setup with a gentle filter (sponge or baffled flow, since they dislike strong current), a heater holding 75-82F, and a tight lid with no large gaps. Keep the water level moderate and leave an air gap at the top, as these fully aquatic frogs must surface to breathe air.
Diet
These frogs are carnivores that feed on small invertebrate foods. Offer sinking frog or carnivore pellets, frozen-thawed bloodworms, brine shrimp, mysis shrimp, and similar small meaty foods, targeting the frogs directly since they are slow, near-sighted feeders that locate food largely by smell and touch. In community tanks, fast tankmates can outcompete them, so spot-feeding near the frogs is often necessary.
Feed adults a few times per week and juveniles more frequently, offering only what is eaten within a few minutes to avoid fouling the water. Avoid overfeeding, which both bloats the frogs and degrades water quality.
Behavior & temperament
African dwarf frogs are peaceful, social, and most comfortable kept in groups; they often hang motionless at the surface in a spread-eagled float, dart up for air, and may perform a humming or singing call (more common in males) at night. They should not be handled, as they are fragile and breathe through delicate skin, and they can be kept with small, non-aggressive fish that will not eat or outcompete them.
A word of caution: they are frequently confused with African clawed frogs (Xenopus), which grow much larger, are aggressive predators, and are restricted or illegal in some regions. True dwarf frogs have four webbed feet (clawed frogs have webbed hind feet and unwebbed, hand-like front feet). Note that most trade animals are H. boettgeri, the closely related H. curtipes, or hybrids of the two, which are very similar in care. Enrichment comes from planted cover, hiding spots, and a stable, well-maintained environment.
Health
The leading causes of illness and death are poor water quality and an uncycled tank, leading to ammonia or nitrite poisoning, plus bacterial infections and dropsy or bloat (severe abdominal swelling that is a sign of disease rather than a disease itself). Skin shedding problems, fungal patches, and chytrid are also seen, especially in stressed or newly imported animals.
Prevention is almost entirely water management: fully cycle the tank before adding frogs, test and maintain zero ammonia and nitrite, perform routine partial water changes with dechlorinated water, and keep temperature stable. Quarantine new frogs and avoid housing them with fin-nippers or large fish. Bloating, floating problems, skin lesions, redness, or appetite loss should be assessed by an aquatic-experienced veterinarian; this entry does not replace veterinary diagnosis.
Tips, DIY & hacks
Because they are slow, near-sighted feeders, target-feed sinking foods (frozen bloodworms, brine shrimp, sinking pellets) with a pipette or feeding dish so faster tankmates don't outcompete them. Provide caves or dense plants for security, and never confuse them with African clawed frogs, which have claws and outgrow community tanks.
