🏠 Enclosure
- Enclosure planning dimensions: 90 x 45 x 45 cm
- Housing: One animal per enclosure
🪨 Substrate and furnishings
Floor space matters more than height. Juveniles can start in modest terrestrial setups, but adults need a strong, easy-to-clean enclosure with room to turn, soak, and burrow safely. Many keepers use enclosures around 90 x 45 cm or larger for big adults, especially males.
The enclosure should include:
- Deep diggable substrate such as a soil-based mix without sharp particles
- One or more sturdy hides
- A broad soaking bowl
- Open ground for feeding response and movement
- Secure furnishings that cannot collapse onto a burrowing frog
Decoration should stay practical. Heavy stones, loose wood piles, and unstable platforms are poor choices because this frog digs forcefully and can undermine them.
💡 Lighting
A normal day-night cycle is sufficient. Bright basking-style lighting is much less important than thermal control at substrate level and the ability to choose sheltered retreats.
For UV planning, treat this species as Ferguson Zone 1. Aim for about UVI 0.5-1.0 in the upper exposed area, while leaving retreats and a gradient down to shaded areas near zero UVI. This usually points to a low-output UVB tube such as a ShadeDweller-style or 2-7% T5, chosen for the enclosure height; measure with a Solarmeter 6.5 when possible, because reflector, mesh, distance, and lamp age change the real exposure.
🌡️ Temperature
This species prefers warmth, but not constant overheating. A daytime range of about 24-30°C works well in many setups, provided the frog can retreat to a cooler area. Night temperatures around 22-25°C are usually suitable.
Suitable approximate values:
- Warm daytime zone: 28-30°C
- General ambient range: 24-28°C
- Night: 22-25°C
Heat should not bake the frog from directly above without escape options. Belly heat through uncontrolled mats can also be risky if it dries the substrate too hard or creates hot spots. Temperatures should always be checked at animal level.
💧 Humidity and water
This species does not need a large aquatic section, but water management still matters. A broad, stable bowl should be available at all times so the frog can soak when it chooses. Because these frogs often drag substrate into the bowl and may foul it quickly, the water should be changed very frequently.
Key points include:
- Use dechlorinated or otherwise amphibian-safe water
- Keep the soaking bowl shallow enough for safe entry and exit
- Replace water promptly after fouling
- Avoid turning the whole enclosure into a wet sludge zone
Aquarium-style filtration is usually unnecessary unless the enclosure includes a much larger water section than normal. Clean manual water changes are more practical in most setups.
Humidity should be moderate rather than extreme. The lower substrate layers should retain some moisture, while the upper surface and at least part of the enclosure should be allowed to dry out between wetter periods.
Good practice includes:
- Keeping a moist zone below the surface
- Allowing a drier upper layer in part of the enclosure
- Avoiding constantly swampy substrate
- Offering clean soaking water at all times
Permanent wetness leads to skin problems, foul substrate, and bacterial trouble. On the other hand, a completely dry setup with no moist refuge can cause dehydration and poor sheds. A moisture gradient works better than uniform dampness.
🪳 Feeding
Pyxicephalus adspersus is an opportunistic carnivore and should be fed a varied diet of appropriately sized prey. Suitable staples include roaches, crickets, earthworms, and other safe feeder invertebrates.
Suitable foods often include:
- Roaches
- Crickets
- Earthworms
- Locusts where available
- Occasional higher-value prey items only in moderation
Juveniles usually need more frequent feeding because they grow quickly. Adults often do well on two or three substantial meals per week, sometimes less for very heavy animals. Appetite is not a safe guide on its own, because this species will often overeat if given the chance.
Calcium should be used regularly, with broader vitamin supplementation added according to the feeder range and product instructions. Vertebrate prey, if used at all, should not become a routine staple because overuse promotes obesity and unbalanced nutrition.
🩺 Health — warning signs
The most common problems in captivity are obesity, impaction, dehydration, rostral and mouth injuries during feeding, and bacterial skin issues associated with dirty wet substrate.
Warning signs include:
- Rapid weight gain and an overly rounded body profile
- Refusal to feed outside seasonal patterns
- Red or irritated skin
- Staying in the water constantly
- Weakness, poor strike accuracy, or abnormal posture
Impaction risk rises when frogs consume large amounts of loose indigestible substrate during feeding. Overheating is another serious threat, especially in simple enclosures with no cool retreat. Any persistent bloating, severe lethargy, skin lesions, or feeding problems should be evaluated by a veterinarian experienced with amphibians.
