🏠 Enclosure
- Use a warm, humid room or secure outdoor pen; small terrariums fail
- Adult footprint: 400 x 300 cm (12 m²); larger animals and groups need more
- Use deep soil, leaf litter, cypress mulch, or clean forest material over a draining base
- Barriers must resist pushing and digging
- Avoid shallow substrate, waterlogged floors, slick surfaces, and exposed untreated wood
🪨 Enclosure furniture
- Open walking lanes, dense visual cover, and several full-body shaded shelters
- Deep leaf-litter zones for burrowing and natural foraging
- Robust edible plants or browse branches
- A large shallow soaking area with easy entry and exit
- Use duplicate shelters, feeding sites, and basking areas for groups
💡 Lighting
- UVB is essential indoors; aim for Ferguson Zone 2 at the basking area
- Preferred setup: T5 HO UVB tube plus a separately controlled basking lamp
- A measured mercury-vapor system may suit a room-sized enclosure
- Check UVI at shell height; replace lamps by measured output and manufacturer guidance
- Direct sunlight is useful in suitable weather; glass and plastic block UVB
- Photoperiod: 10-12 h with modest seasonal adjustment; no night light
🌡️ Temperature
Basking spot: 30-32 °C
Warm zone: 24-29 °C
Cool zone: 22-24 °C
Night: 20-24 °C
Maintain warm humid air with a clear gradient
Measure basking surfaces with an infrared thermometer and ambient zones with digital probes
Use guarded, thermostatically controlled heat; avoid heat rocks and cold wet floors
💧 Humidity & water
- General humidity target: 70-90%, with local short-term access around 80-95%
- Pair high humidity with ventilation and drainage
- Provide a large shallow soaking area; replace fouled water
- Keep deep substrate evenly moist below the surface, not saturated
- Monitor juveniles and imported animals for hydration and shell condition
🥬 Diet
Feed freely:
- Broadleaf weeds, grasses, plantain, squash leaves, hibiscus, mulberry leaves, and safe seasonal browse
In moderation:
- Mixed leafy vegetables, edible fungi or forest foods, and soaked high-fiber tortoise pellets
Avoid:
- Fruit-heavy feeding, animal food as a staple, dog or cat food, bread, dairy, and spoiled vegetation
Supplements:
- Plain calcium or cuttlefish bone; use multivitamins sparingly and maintain effective UVB
🩺 Health — warning signs
- Dry skin, sunken eyes, or hard urates → insufficient humidity or water access
- Shell abrasions or limb injury → cramped housing or sharp barriers
- Foul skin, shell lesions, or persistent odor → dirty water, poor drainage, or infection
- Nasal discharge or wheezing → respiratory disease or unsuitable temperature
- Distorted growth → excess calories or poor calcium and UVB balance
- Diarrhea or sustained weight loss → parasites, infection, or poor quarantine
Consult a reptile-experienced veterinarian for breathing signs, injury, shell lesions, diarrhea, or sustained weight loss.
