Budgett's frog is a chubby, flat, largely aquatic frog with a wide mouth, tiny eyes set on top of the head, and a famously feisty, screaming defensive display. Hardy and full of personality, it is a popular oddball pet that must be housed alone due to extreme cannibalism.

Part of the Aquatic amphibians
Fully or largely aquatic amphibians kept in cycled, well-filtered freshwater aquariums. They surface to breathe, prefer gentle current and hiding spots, and are not handling animals.
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.

Minimum
Semi-aquatic floor terrarium
20-gal long (30 × 12 × 12 in)
Lepidobatrachus laevis is a fully aquatic ambush predator with soft skin — strict water quality is critical. Solo housing only (cannibalistic). 20-gal long with ~6 in soft, dechlorinated water, gentle filter (or daily 50% water changes), low light, hides, 72–80 °F.

Recommended
Larger aquatic enclosure
29 gal (30 × 12 × 18 in)
Wider tank with 6–8 in soft water, gentle sponge filter, multiple bottom hides, and a small land slope for emergence if needed. Budgett's frogs are skin-breathers — never use copper pipes/chemicals near the water.

Ideal
Planted aquatic enclosure
40-gal breeder planted
Planted aquatic enclosure with soft sand substrate, hardy plants (Anubias, Java fern), gentle filter, and excellent water quality (low TDS, neutral pH). Supports the species' famous 'screaming' display when threatened.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Amphibian eggs are soft, jelly-coated spheres laid in or near water — in floating clutches, strings, or foam nests depending on the species. The dark embryo is visible within the clear gel as it develops.

Tadpole / Larva
The aquatic larva (a tadpole in frogs/toads, a gilled larva in salamanders and newts) breathes through gills and feeds and grows in water. Frog/toad tadpoles are limbless at first, then sprout hind then front legs as metamorphosis nears.

Juvenile (froglet / eft)
At metamorphosis the animal develops legs and lungs and typically leaves the water as a froglet or, in many newts, a terrestrial eft. It resembles a small adult but is not yet sexually mature and its coloration may still be changing.
Adult
Adults reach full size and breeding condition, with the species' mature skin coloration and pattern. Many amphibians return to water to breed and can show seasonal or sex-specific changes such as nuptial coloration or crests.
Habitat & enclosure
House strictly one frog per enclosure, as they are aggressively cannibalistic. A semi-aquatic setup with a water section deep enough to submerge the frog plus a shallow land/haul-out area works well; an aquarium of about 40-75 L (10-20 gal) suits one adult. Keep water shallow enough that the frog can rest on the bottom and reach the surface easily. Maintain water at 24-28 C (75-82 F), pH near neutral, well dechlorinated. They naturally aestivate buried in mud during dry seasons, so a substrate they can dig into is appreciated for a fully aquatic-to-shallow setup.
Substrate
For semi-aquatic setups, fine sand or a bare bottom is easiest to keep clean; for a more naturalistic enclosure provide a soft, diggable substrate (sand/soil mix) that allows burrowing/aestivation behavior. Avoid loose gravel that could be swallowed during feeding.
Equipment & setup
A reliable aquarium heater, gentle filtration or a strict water-change regimen, a secure lid, and a dechlorinator are essential. No UVB is required, though low ambient lighting and a day/night cycle are beneficial. A water test kit helps monitor ammonia and nitrite in this high-waste species.
Diet
Voracious ambush carnivores with a huge appetite. Juveniles eat insects (crickets, dubia roaches), worms, and small fish; adults take earthworms, large insects, fish, and the occasional appropriately sized rodent (sparingly). Feed juveniles every 1-2 days and adults 2-3 times weekly, adjusting to keep a healthy (not obese) body. Use tongs and watch fingers, as they lunge and bite hard with bony tooth-like odontoids.
Behavior & temperament
Bold and defensive for an amphibian: when threatened they inflate, rise up, open the wide mouth, and emit a loud scream, and they will readily bite. They are not a handling pet; the bite is painful and handling stresses their permeable skin. Despite the drama they are hardy, long-lived, and interactive feeders that learn to associate keepers with food. Always keep them solitary.
Health
Generally robust but prone to obesity from overfeeding and to skin/bacterial infections (red-leg) and fungal issues from poor water quality. Bloat and metabolic problems can occur. Maintain clean water, dechlorinate, and avoid overfeeding fatty prey. Handle only when necessary with wet, clean, powder-free gloves or wet bare hands.
Tips, DIY & hacks
Keep water relatively shallow for younger frogs so they reach air easily. Feed with long tongs to avoid bites. A seasonal cool, drier rest can trigger breeding but is not required for pet keeping. Because they foul water quickly, frequent partial water changes (or strong filtration) are key. Never cohabitate, even briefly.
