Crested Gecko Breeding: The Basics
| Sexual maturity | ~12–18 months |
| Clutch size | 2 eggs, repeated every 3–4 weeks |
Timing
Most experienced breeders wait until females are well past minimum maturity weight and in strong body condition, typically 12–18+ months old, before breeding given the metabolic cost egg production places on a genuinely small species.
Small, frequent clutches
Unlike larger reptiles laying big clutches, crested geckos lay just 2 eggs per clutch, but can lay repeatedly through a breeding season roughly every 3–4 weeks — a real ongoing metabolic demand on the female that needs monitoring for calcium depletion.
Infertile clutches happen without a male
Female crested geckos can develop and lay infertile eggs even with zero male contact, a normal reproductive cycle rather than a sign anything is wrong, though egg-binding risk should still be monitored.
Not a beginner project
Managing incubation, potential egg-binding, and finding good homes for hatchlings takes real preparation — worth researching thoroughly before attempting.

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.
