🏠 Enclosure
- Indoor, locked enclosure for one adult; minimum 150 × 75 × 120 cm.
- Increase for a large female; seal cable routes and anchor every support.
- Substrate: 8-12 cm soil/coir and orchid or cypress bark with leaf litter; paper in quarantine.
- Avoid cedar, aromatic wood, sharp bark and unstable heavy decor.
🪨 Enclosure furniture
- Thick horizontal and diagonal branches, elevated shelves and cork tubes.
- Covered ground retreats plus enough open floor to rest without climbing.
- Local humid hide, dense visual cover and a stable water bowl.
- Test branches and plant anchors above the snake’s full weight.
💡 Lighting
- Low-level UVB recommended in a Ferguson Zone 1-style gradient.
- Bright visible light with deep shade; do not illuminate the whole enclosure uniformly.
- Guard every internal lamp.
- Photoperiod: 11-13 hours; replace UVB by measured output/manufacturer schedule.
🌡️ Temperature
Basking spot: 29-31 °C
Warm zone: 24-28 °C
Cool zone: 22-25 °C
Night: 20-24 °C
Thermostat heaters and measure at ground and perch level.
The species does not need constant extreme heat; inability to cool is dangerous.
Seasonal breeding cooling is not routine pet care.
💧 Humidity & water
- General daily cycle: 60-80%; local shed humidity 75-85%.
- Mist in the evening, maintain strong cross-ventilation and allow partial drying by day.
- Stable clean bowl; change whenever contaminated.
- Avoid constant condensation, stagnant air and waterlogged substrate.
🐁 Diet
Feed freely:
- Frozen-thawed mice or rats; juveniles every 7-10 days, adults every 14-21 days.
In moderation:
- Captive-bred chicks; adjust breeding females by body condition, not a fixed surplus.
Avoid:
- Live rodents, oversized/frequent prey and routine power-feeding.
Supplements:
- Whole prey requires no routine dusting; record weight monthly.
🩺 Health — warning signs
- Wheezing, mucus or open-mouth breathing → respiratory infection, poor airflow or temperature.
- Patchy shed or retained spectacles → dehydration or inadequate local humidity.
- Blisters and ventral discolouration → saturated dirty substrate.
- Burns → accessible heat source or thermostat failure.
- Obesity → prey too large or frequent.
- Prolonged fasting with weight loss → stress, reproductive state or disease.
- Dystocia, stillbirths or retained material → reproductive emergency.
- Document mismatch → stop the transaction and contact the CITES authority.
Use a reptile-experienced veterinarian for breathing, weight, shedding or reproductive signs; preserve original legal documents for life.
