Crested Gecko Behaviour: What They're Telling You
| Activity pattern | Nocturnal |
| Tail regrowth | None — permanent loss |
Nocturnal activity
Most feeding, exploring, and activity happens after dark. A gecko tucked into foliage and inactive all day is behaving completely normally, not showing signs of illness.
Jumping and escape attempts
This species is a strong, confident jumper and will readily launch off a hand or an open enclosure lid if startled. Handle low to the ground over a soft surface, and keep the enclosure securely closed at all times.
Tail dropping
A dropped tail is usually a response to being grabbed by the tail, sudden startling, or occasionally cohabitation stress. Since it won't grow back, gentle handling that supports the whole body (never restraining any single part) meaningfully reduces the risk.
Eye licking
Without moveable eyelids, this species licks its own eyes clean with its tongue — completely normal grooming behaviour, not a sign of thirst or distress on its own.

A single adult crested gecko needs a minimum 18"x18"x24" front-opening, well-ventilated enclosure — taller matters more than wider since this species is highly arboreal — furnished with cork bark, branches, and dense foliage for climbing.
A complete crested gecko setup needs a tall 18"+ front-opening enclosure, cork bark and branches for climbing, coco fibre/moss substrate, a misting routine to hold 50–80% humidity, and complete CGD powder — no heat lamp is required in most homes.
Hatchlings can start in a small (roughly 8"x8"x12") enclosure to make food easier to find, juveniles move up around a few months old, and adults need a minimum 18"x18"x24" vertical enclosure.
Crested geckos generally do best at normal room temperature, roughly 72–78°F, and can suffer heat stress above about 82°F. Most homes need no basking bulb or heat mat at all — just monitoring during hot weather.
Low-level UVB (roughly 5–6% output) is increasingly recommended as good practice, though it isn't strictly mandatory for crested geckos the way it is for a strongly basking desert species — their diet's built-in D3 from CGD covers much of the gap.
Crested geckos need roughly 50–80% humidity, achieved through misting once or twice daily, with good ventilation to prevent the dampness from turning stagnant.
