Crested Gecko Licking Behaviour Explained

Quick answer: Crested geckos lick to investigate scent and taste in their environment (including a keeper's hand, which is normal and not aggression) and also lick their own eyes since they lack eyelids, using the tongue to clear debris and keep the eye moist.
Common targetsHands, glass, own eyes
MeaningScent investigation, eye cleaning

Licking surfaces near food or supplement dust is also a way of sampling for anything worth eating. It's one of the more harmless and common behaviors keepers observe.

Crested Gecko Enclosure: What You Actually Need

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.

Crested Gecko Setup Checklist: Everything Before Day One

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.

Crested Gecko Tank Size Guide: By Age

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 Gecko Heating: Why You Probably Don't Need Any

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.

Crested Gecko UVB: Is It Actually Necessary?

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 Gecko Humidity: Why It Needs to Be High

Crested geckos need roughly 50–80% humidity, achieved through misting once or twice daily, with good ventilation to prevent the dampness from turning stagnant.
