🏠 Enclosure
- One adult: minimum 120 x 60 x 60 cm; 150 cm length preferred
- House singly; social pressure may be subtle before injury appears
- 15-20 cm compactable sandy soil: about 50% fine sand, 30% pesticide-free soil, 20% clay
- Place heavy rocks on the solid base before substrate
- Avoid calcium sand, walnut shell, wood chips, dust, loose gravel, and adhesive surfaces
🪨 Enclosure furniture
- Broad body-sized basking platform and lower cooler ledges
- Several tight rock-like crevices at different temperatures
- Low climbing routes, visual barriers, and one protected slightly moist deep refuge
- Stable shallow water bowl and clean feeding slab or dish
💡 Lighting
- Strong linear T5 UVB is essential; target measured UVI 4.5-6 at the basking back
- Bright white daylight across most of the enclosure
- UVB and heat overlap on the warm side; preserve shade and dark cracks
- Replace lamps from measurements or manufacturer schedule
- Photoperiod: about 12 h active season; reduce gradually toward 10 h only for planned cycling
🌡️ Temperature
Basking spot: 48-55°C
Warm zone: 30-35°C
Cool zone: 24-29°C
Night: 18-24°C
Use several halogen floods for a broad heat patch
Measure surfaces by infrared thermometer and air/hides by digital probes
Avoid heat rocks, unregulated mats, and direct sun through glass
💧 Humidity & water
- General humidity: 20-35%; dry, well-ventilated surface
- Keep only a selected deep refuge slightly moist; do not wet the whole enclosure
- Small clean water bowl always available; change when soiled
- No routine soaking; investigate dehydration through diet, setup, and veterinary assessment
🥬 Diet
Feed regularly:
- Dandelion, plantain, sow thistle, endive, chicory, turnip or mustard greens, mulberry, hibiscus, safe clover and flowers
In moderation:
- Squash, green beans, carrot, soaked herbivore pellets, lentils and small seeds
Avoid:
- Routine insects or other animal protein, dog/cat food, frequent fruit, and pesticide-treated plants
Supplements:
- Plain calcium lightly 1-2x/week; multivitamin by label and measured UVB; do not stack fortified products
💤 Brumation
- Optional, mainly for healthy established breeding adults
- Never cool juveniles, thin, ill, dehydrated, new, or parasite-positive animals
- Reduce daylight and food gradually; night may approach 14-18°C while daytime basking remains available
- Track weight and condition; stop and consult a reptile veterinarian if either declines
🩺 Health — warning signs
- Soft jaw, tremors or weak limbs → possible UVB/calcium disorder
- Skin retained on toes or tail → dehydration or poor refuge gradient
- Nasal discharge or abnormal breathing → cold, damp conditions or respiratory disease
- Weight loss, diarrhea or poor condition after import → possible parasites or systemic illness
- Repeated digging, straining or weakness in a female → possible retained eggs
Consult a reptile-experienced veterinarian for severe weakness, swelling, breathing signs, burns, persistent weight loss, or reproductive straining.
