Mourning Gecko Behaviour: What They're Telling You

Quick answer: Mourning geckos are mostly nocturnal (expect daytime sleeping), excellent jumpers prone to leaping when startled, will drop their tail (which regrows) under stress or rough handling, and lick their own eyes to clean them — all completely normal.
Activity patternNocturnal
Tail regrowthYes — regrows over weeks to months

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 colony stress. It will regrow over the following weeks to months, but it's still a genuine stress event, so 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.

Mourning Gecko Enclosure: What You Actually Need

A single adult mourning gecko needs a minimum 12"x12"x18" 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.

Mourning Gecko Setup Checklist: Everything Before Day One

A complete mourning gecko setup needs a tall 18"+ front-opening enclosure, cork bark and branches for climbing, coco fibre/moss substrate, a misting routine to hold 60–80% humidity, and complete MRP powder — no heat lamp is required in most homes.

Mourning Gecko Tank Size Guide: By Age

Hatchlings can start in a small (roughly 5"x5"x8") enclosure to make food easier to find, juveniles move up around a few months old, and adults need a minimum 12"x12"x18" vertical enclosure.

Mourning Gecko Heating: Why You Probably Don't Need Any

Mourning geckos generally do best at normal room temperature, roughly 75–82°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.

Mourning 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 mourning geckos the way it is for a strongly basking desert species — their diet's built-in D3 from MRP covers much of the gap.

Mourning Gecko Humidity: Why It Needs to Be High

Mourning geckos need roughly 60–80% humidity, achieved through misting once or twice daily, with good ventilation to prevent the dampness from turning stagnant.
