🏠 Enclosure
For one adult, use at least 120 x 90 x 180 cm; a compatible pair or established family unit needs substantially more usable volume and duplicate resources. Height counts only when trunks, branches, feeding stations, hides, and thermal choices fill it.
🪨 Substrate and furnishings
Build a connected canopy of thick trunks, thinner grip branches, cork hollows, shelves, vines, and dense visual cover. The tail must be able to wrap around safe supports. Include hides and feeding ledges at warm, intermediate, and cool heights.
Use 8-12 cm of moisture-buffering soil and leaf litter over drainage. Select non-toxic plants that can survive a heavy browsing skink, and verify every plant before use. Protect lamps and cables; secure branches so a 1 kg animal cannot rotate or pull them down.
💡 Lighting
Provide bright broad-spectrum visible light and a linear T5 UVB lamp over part of the canopy. Plan around Ferguson Zone 2, with measurable low-to-moderate UV at accessible upper branches and deep shade next to it. Use an 11-13 hour photoperiod and no visible light at night.
Do not create one exposed, scorching perch. This species often regulates by moving through filtered warmth and shade. Replace lamps on schedule or according to meter readings.
🌡️ Temperature
- Basking spot: 30-34 °C
- Daytime air: 24-28 °C
- Cool zone: 22-25 °C
- Night: 20-24 °C
💧 Humidity and water
Maintain about 60-80% relative humidity, rising to 70-85% after misting and during shedding, with steady cross-ventilation. Mist foliage so drinking droplets are available, then allow surfaces to partly dry. Saturated substrate and still air encourage skin and respiratory disease.
Provide a heavy clean water bowl and, if practical, a second elevated bowl. Change water daily. A drainage layer or drainable substrate system is strongly recommended in planted enclosures.
🪳 Feeding
The diet should be browse-led and herbivorous. A zoo diet sheet uses fresh browse for 50-75% of each feed, commercial greens for less than 25% when browse is unavailable, and fruit around 25%. For home care, prioritize safe pesticide-free leaves and flowers, dark leafy greens, and varied vegetables; keep fruit limited rather than making it the sweet staple.
Useful foods include mulberry, hibiscus, grapevine and other verified safe browse, dandelion, endive, escarole, mustard or turnip greens, squash, green beans, peppers, and a smaller rotation of papaya, fig, berries, or melon. Avoid avocado, rhubarb, onion-family foods, unknown ornamental plants, and animal protein as a routine food.
Offer adults fresh food three to five times weekly and growing or reproductive animals more often. Use calcium and a controlled reptile-herbivore multivitamin according to UVB and product guidance. Track body weight, droppings, and food selection; repeated preference for fruit should not dictate the menu.
☠️ Safety
Handle only for health checks and controlled transfers. Allow the skink to grip a branch or padded forearm, support the torso, and never pull the prehensile tail free. A defensive adult has a powerful bite that can cause deep crushing injury.
Use a secure shift box for veterinary transport. Children should not handle this species.
🩺 Health — warning signs
Common failures include obesity or nutrient imbalance from fruit-heavy diets, metabolic bone disease, dehydration, retained shed around toes, skin infection in stagnant wet housing, burns, falls, bite wounds from introductions, and stress-related appetite loss. Recently traded animals may carry internal or external parasites.
Watch for weak grip, a soft or swollen jaw, tremors, tail or toe constriction, wheezing, nasal bubbles, persistent hiding, exclusion from food, abnormal feces, or sustained weight change. Quarantine and reptile-veterinary assessment are essential before social introductions.
