📋At a Glance
African bullfrogs are among the largest frogs — squat, powerful, endlessly hungry ambush predators (males dwarf females). They're hardy and easy to keep, remarkably long-lived, and aestivate in a cocoon through dry spells. But they're big, have a strong bite and delicate skin, so they're a characterful display animal, not a frog to handle.
Best for: keepers wanting a big, hardy, characterful (if grumpy) frog with real presence.
💷Costs & Getting Hold of One
The animal
£30–£80.
Full setup
£150–£500 (terrarium, low heat, deep moist substrate, shallow water).
Ongoing costs
Low–moderate — insects and occasional larger prey.
Availability
Fairly easy; widely captive-bred.
These are minimums, not budgets. The low end still has to meet the animal's needs — proper UVB, a heat gradient, space and filtration are not optional extras. A vivarium alone can cost £250–£300+, and a tortoise's UVB lamp alone is often ~£100. Price the whole setup before you commit to the animal.
Buying tip: Choose a plump, alert frog. They grow fast, so plan for a large adult (males especially).
🏠Enclosure & Where to Keep It
A large, sedentary, burrowing ground frog — floor space and deep moist substrate.
Adult
90×45×45 cm for a big adult.
Substrate depth
Deep, moist, dig-able substrate to burrow into.
Water
A large shallow dechlorinated water area; keep substrate moist.
Housing
Always alone — they eat tank-mates.
House singly and never on gravel; keep the water shallow and clean.
🌡️Temperature, Lighting & Humidity
Temperature
24–28 °C, cooler at night; gentle heat only.
Lighting / UVB
Low UVB optional/beneficial. 12-hour cycle.
Humidity
High (60–80%); keep substrate moist.
Bedding / substrate
Deep moist coco fibre/soil mix.
🍽️Diet, Supplements & Feeding
A voracious carnivore — insects, worms and occasional vertebrate prey.
Staple
Dusted insects (crickets, dubia, locusts) and worms.
Larger items
Occasional pinky/fuzzy for large adults, sparingly.
Frequency
Juveniles most days; adults every few days to weekly.
Supplements
Dust with calcium (+ D3/multivitamin per schedule).
They'll gorge, so feed measured portions to avoid obesity. Tong-feed and keep fingers clear of the powerful mouth.
✨Grooming, Shedding & Additional Needs
No grooming; keep substrate moist. They aestivate (dry-season dormancy) in a skin cocoon if conditions dry out.
If it forms a cocoon and buries, that's natural aestivation — don't force it out; correct humidity to bring it round gently.
🖐️Handling & Interaction
Not a handling animal. Delicate skin plus a big, willing bite. A display frog with a big personality.
How to handle
Interact by tong-feeding and observation. Move only when necessary with clean wet hands, away from the mouth.
✅ Do
Tong-feed and keep fingers clear.
House alone.
Keep substrate moist and clean.
Feed measured portions.
Wash hands after contact (salmonella).
⛔ Don't
Don't handle — bites and delicate skin.
Don't house with anything.
Don't keep on gravel.
Don't overfeed.
Don't force it out of aestivation.
🦎Fun Facts
One of the largest frogs, with males far bigger than females.
Males guard the tadpoles — unusual parental care in frogs.
Aestivates in a cocoon of shed skin through dry spells.
Astonishingly long-lived for a frog — decades.
Native to sub-Saharan Africa's seasonal wetlands.
⭐Overall Verdict
A hardy, giant, characterful frog that's easy to keep but full of attitude — big appetite, big bite, delicate skin. Keep it alone, moist and measured on food, treat it as a display, and it's a remarkable, long-lived animal.
