Green Pixie Frog Care Guide
The Green Pixie Frog (Pyxicephalus adspersus), also known as the African Bullfrog, is the second-largest frog species in the world and one of the most impressive amphibians you can keep. Native to sub-Saharan Africa, these frogs are bold, aggressive, long-lived, and have enormous appetites to match their enormous size. Adult males can exceed 9 inches and weigh over 2 pounds. They are not beginner frogs — they bite hard, eat a lot, and require proper husbandry — but for the keeper ready for the challenge, they are endlessly fascinating.
At Ohio Pet Depot, we carry Green Pixie Frog Babies and Green Pixie Frog Juveniles. This guide covers everything you need to keep them healthy from juvenile to adult.
⚠️ Bite Warning
Green Pixie Frogs bite — hard. Unlike most frogs, they have vomerine teeth (bony tooth-like projections on the upper jaw) and a powerful jaw. Large adults can cause serious lacerations. Never hand-feed directly — always use long feeding tongs. Handle with care and respect; this is not a frog to be casual with.

Enclosure Setup
Size
Green Pixie Frogs grow large and need appropriately sized enclosures as they mature:
- Juvenile (under 3 inches): 10-gallon minimum
- Sub-adult (3–6 inches): 20-gallon long minimum
- Adult male: 40-gallon breeder minimum; 75-gallon preferred
- Adult female: 20–30 gallon (females stay significantly smaller)
Never house two males together — they are highly aggressive toward each other and cannibalism is documented in the wild. Males will eat smaller frogs, including females outside of breeding season.
Substrate
Use a deep, moisture-retaining substrate that allows burrowing — Pixie Frogs spend much of their time partially buried:
- Zoo Med Eco Earth Loose Coconut Fiber — excellent moisture retention, soft for burrowing, easy to spot-clean
- Zoo Med Eco Earth Compressed Coconut Fiber — same great substrate in brick format
- A coconut fiber + topsoil mix (no fertilizers or pesticides) works well for larger enclosures
Maintain 4–6 inches of depth for adults. Keep substrate damp but not waterlogged — like a wrung-out sponge.
Water Dish
Provide a large, shallow water dish the frog can fully sit in. Pixie Frogs absorb water through their skin — they do not drink. For large adults, a plastic storage container or cat litter box works well as a soak dish. Change water daily — these frogs defecate in their water constantly. Use dechlorinated or filtered water only.
Hides & Decor
Keep it simple — Pixie Frogs will bury themselves and use the substrate as their primary hide. A cork bark flat or half-log gives them an above-ground option. Avoid complex decor that makes cleaning difficult; these are messy animals that require frequent spot-cleaning.
Temperature & Lighting
Temperature
| Zone | Temperature |
|---|---|
| Ambient (daytime) | 75–85°F |
| Warm side | 82–88°F |
| Cool side | 72–78°F |
| Nighttime low | 68–74°F |
If supplemental heat is needed, use a Fluker's Ceramic Heat Emitter on a thermostat. Never use an under-tank heater without a thermostat — burrowing frogs can be burned by unregulated bottom heat. The Fluker's Deep Dome Lamp is a solid fixture option.
UVB Lighting
UVB is not strictly required but is beneficial for long-term health and vitamin D3 synthesis. A Zoo Med ReptiSun Compact Fluorescent UVB Bulb (5.0) on a 12-hour cycle is a good option. Keep the light at least 12" from the frog's resting area. If not using UVB, ensure vitamin D3 is included in your supplement rotation.
Photoperiod
Maintain a 12-hour light / 12-hour dark cycle. Pixie Frogs are primarily nocturnal and most active after dark.
Humidity
Target 60–80% humidity. The large water dish and damp substrate are the primary humidity sources. Mist the enclosure once daily, preferably in the evening.
Estivation warning: If the enclosure becomes too dry for an extended period, Green Pixie Frogs will form a cocoon of shed skin layers and enter estivation (dry-season dormancy). This is a survival mechanism, not a health crisis if caught early — but chronic dryness leading to estivation in captivity indicates a husbandry problem. Restore humidity and provide a soak immediately if you find your frog cocooned.
Diet & Feeding
Green Pixie Frogs are aggressive, voracious carnivores. In the wild they eat insects, worms, small mammals, birds, lizards, and other frogs. In captivity, a varied insect and worm diet is the foundation, with rodents added for large adults.
Feeder Insects & Worms (Staples)
- Banded Crickets — excellent staple for juveniles and sub-adults
- Dubia Roaches — nutritionally superior staple; highly accepted at all life stages
- Nightcrawlers — outstanding protein source; excellent for all sizes
- Red Worms — ideal for juveniles and as variety feeders
- Superworms — great for sub-adults and adults; high protein
- Mealworms — good variety feeder; offer in moderation
Treat Feeders (Occasional)
- Hornworms — high moisture, great for hydration; offer occasionally
- Wax Worms — high fat; use sparingly as a treat
- Frozen Feeder Rats (pinky/fuzzy/hopper) — appropriate for large adult males only; offer no more than once every 2–4 weeks. Rodents should be a supplement, not a staple — too much mammalian protein causes obesity and fatty liver disease in frogs
Feeding Schedule
| Age / Size | Frequency | Prey Size & Type |
|---|---|---|
| Juvenile (under 2 inches) | Daily | Small crickets, red worms, small dubias |
| Sub-adult (2–5 inches) | Every 2–3 days | Medium-large crickets, dubias, nightcrawlers, superworms |
| Adult male (5+ inches) | Every 4–7 days | Large dubias, nightcrawlers, superworms; occasional pinky/fuzzy rodent |
| Adult female | Every 3–5 days | Large crickets, dubias, nightcrawlers; no rodents needed |
Always use tongs — never hand-feed. Large Pixie Frogs strike with speed and force; a bite from an adult male is painful and can break skin.
Overfeeding warning: Like Pac-Man Frogs, Pixie Frogs have no satiation limit. Obesity is extremely common in captive animals and leads to fatty liver disease and shortened lifespan. Stick to the schedule above.
Supplements
Dust all feeder insects with Zoo Med Repti Calcium at every feeding for juveniles and every other feeding for adults. Use a multivitamin supplement (with vitamin D3 if not using UVB) once every 1–2 weeks. Gut-load crickets 24–48 hours before feeding with Fluker's Orange Cube Cricket Diet.
Handling & Temperament
Green Pixie Frogs are not a handling pet. They are display animals with aggressive feeding responses and a genuine bite risk.
- They will bite without warning — large adults have vomerine teeth and a powerful jaw capable of causing lacerations. Treat every interaction with respect
- Skin absorption: Always wash hands thoroughly before and after any contact. Never handle with lotions, soaps, or insect repellent on your hands
- Use damp hands or gloves if you must move the frog — dry hands damage amphibian skin
- Cup from below — never grab from above or squeeze
- Most Pixie Frogs will never fully tame down — their appeal is in observation and feeding response, not interaction
Health & Common Issues
| Issue | Signs | Cause / Action |
|---|---|---|
| Estivation / Dehydration | Cocoon of shed skin, sunken eyes, lethargy | Dry enclosure; soak immediately in shallow dechlorinated water; restore humidity |
| Obesity / Fatty liver disease | Extremely bloated, lethargic, loss of appetite | Overfeeding or too many rodents; reduce frequency, eliminate fatty prey |
| Red Leg Syndrome | Reddening of legs and belly, lethargy | Bacterial infection from dirty water/substrate; full clean; vet visit — antibiotics may be needed |
| Impaction | No defecation, distended abdomen, lethargy | Ingested substrate or oversized prey; warm soak; vet visit if no improvement |
| Metabolic Bone Disease (MBD) | Soft jaw, difficulty catching prey, lethargy | Calcium/D3 deficiency; correct supplementation immediately; vet visit |
| Chytrid fungus | Skin sloughing, lethargy, loss of righting reflex | Serious fungal disease; isolate immediately; vet visit — antifungal treatment required |
Lifespan commitment: Green Pixie Frogs can live 20–40+ years in captivity. This is a decades-long commitment. Make sure you are prepared for the long haul before bringing one home.
Dechlorinated water only — always use filtered or dechlorinated water for the water dish and misting. Chlorine and chloramines are absorbed through the skin and cause cumulative organ damage.
Quarantine all new animals for 60–90 days before housing near any other amphibians.
