Overview
Crested geckos are arboreal lizards that require vertical space and carefully managed humidity levels.
Feeding Behavior
- Omnivorous diet
- Many keepers use quality prepared crested gecko diet plus insects
- Most active around dawn/dusk; timing affects feeding behavior
Important Considerations
- Monitor humidity with a hygrometer
- Avoid keeping enclosure constantly saturated
- Provide adequate vertical climbing space
Supplements & Habitat Notes
- If insects are offered, typical reptile feeder supplementation patterns may apply (calcium/vitamins)
- Supplementation strategy depends on diet completeness and UVB usage
Best Setup
- Arboreal and crepuscular: use a vertical enclosure with dense climbing routes and a top-to-bottom temperature and light gradient.
- Minimum adult enclosure: 45 x 45 x 60 cm (18 x 18 x 24 in). Larger is better.
- Young geckos under 12 g often do better in a smaller grow-out enclosure until they can navigate a full adult tank.
- Use a secure, escape-proof lid or door with good airflow (vents plus a screen top) while still supporting humidity cycles.
- Build dense structure with branches, vines, cork bark, and foliage at multiple levels for climbing routes and shaded resting zones.
- Place a feeding ledge with cups mid-to-upper levels, and provide a water dish. Many cresties drink droplets from misted surfaces.
- Temperature gradient: top area 28-29 C, bottom area 21-24 C, night 18-22 C.
- Avoid sustained temperatures above about 29 C to prevent heat stress.
- Use a consistent day and night cycle. Low-level UVB can be beneficial with shaded areas available; target UVI 1.0 to 2.0 at the basking branch.
- Create a photogradient from light to shade; medium output 5-7 percent UVB is commonly placed at the top when used.
- Humidity should cycle rather than stay wet: aim for 60-80 percent, then allow it to dry to about 40-50 percent before the next misting.
- Many keepers add a night humidity spike (often 80-90 percent or higher for a few hours) via evening misting.
- Use 5-10 cm (2-4 in) of moisture-friendly substrate like coco fiber or a naturalistic mix; leaf litter is optional.
- A drainage layer is optional and mainly for bioactive builds; ventilation and misting cycles matter more for simple setups.
