Crested Gecko Egg Incubation Guide

Quick answer: Crested gecko eggs typically incubate at room temperature (72–78°F) with high humidity in a suitable medium, hatching in roughly 60–150 days depending on temperature — sex is largely genetic, not incubation-temperature-determined, unlike some other reptile species.
Incubation temperature~72–78°F (room temp)
Incubation length~60–150 days

Temperature and humidity

Unlike species needing precisely controlled warm incubation, crested gecko eggs can be incubated at normal room temperature (roughly 72–78°F) with high humidity in a vermiculite or perlite medium — a genuinely lower-effort incubation process than many reptile species.

Incubation length

Expect a wide range, roughly 60–150 days depending on temperature — cooler incubation extends the timeline considerably, which is one reason room-temperature incubation is popular and low-stress for this species.

Sex is largely genetic

Unlike species with strong temperature-dependent sex determination, crested gecko sex is understood to be largely genetically determined rather than set by incubation temperature — don't expect to influence hatchling sex ratio through temperature the way some other reptile keepers do.

Candling and checking

Eggs can be gently candled a few weeks in to check for development versus a clearly bad egg — handle minimally and never rotate once placed.

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.
