Enclosure

Housing & setup

Getting the enclosure right before you bring a gecko home makes everything easier. Temperatures, substrate, hides — these aren't optional extras, they're the baseline for a healthy animal.

Skip the heat equipment — most homes don't need it. Unlike many popular pet reptiles, crested geckos generally do best at normal room temperature and can suffer heat stress above roughly 82°F. Adding an unnecessary basking bulb or heat mat is a common beginner mistake for this species, not a requirement.
Temperature & humidity
Safe ambient range
72–78°F

Normal room temperature works for most homes — no basking bulb or heat mat is usually needed. The danger here is heat, not cold: sustained temperatures above roughly 82°F risk lethargy and appetite loss.

Humidity target
50–80%

This is a humid forest species, not an arid one — maintained through misting once or twice daily, with good ventilation to stop that dampness turning stagnant.

Ventilation matters as much as misting. Mesh sides or a well-ventilated screen top let humid conditions stay healthy instead of turning into stagnant, mould-prone dampness. A largely sealed glass enclosure works against the humidity balance, not for it.
Vertical furnishing
Cork bark & branches

The single most important furnishing category for this species. Crested geckos are highly arboreal and spend nearly all their time off the ground — fill the enclosure with cork bark rounds, flats, and grapevine or manzanita branches, not floor decor.

Dense foliage

Live or artificial leafy cover gives a naturally shy, mostly nocturnal species places to feel secure during the day. Bromeliads, orchids, and creeping fig all work well and tolerate the humidity this enclosure needs.

Mid-height feeding ledge

Crested geckos feed at height in the wild — mounting the CGD dish partway up the enclosure rather than on the floor better matches natural feeding behaviour and keeps food away from substrate contamination.

Substrate options
Coconut fibre (eco earth) + sphagnum moss topper

The standard for a humid bioactive crested gecko setup. Holds moisture well, supports live plants, and a springtail/isopod clean-up crew if running fully bioactive. Change or refresh regularly to prevent mould buildup.

Safe
Paper towel

Best for hatchlings, sick geckos, or quarantine. Easy to monitor and replace, though not visually appealing or humidity-retentive long-term.

Safe
Sphagnum moss (as primary layer)

Excellent moisture retention for humidity-dependent species. Keep damp, not soaking, and replace if it starts to smell or grow mould.

Safe
Reptile carpet

Retains less humidity than coco fibre and can harbour bacteria if not washed frequently. Claws can occasionally catch in loose fibres. Acceptable short-term but less ideal long-term for this species.

Caution
Loose substrate for hatchlings feeding on crickets

A hatchling hunting live crickets on loose substrate can accidentally ingest particles along with prey. Use paper towel for very young geckos being fed live insects, switching to bioactive substrate once established and mostly on CGD.

Caution
Sand

Not suited to this species at all — wrong humidity profile for a substrate that needs to stay damp, and carries an impaction risk if ingested with prey. There's no good reason to use sand in a crested gecko enclosure.

Avoid
Walnut shell

Sharp edges can lacerate the digestive tract and cause severe impaction if ingested. Avoid entirely.

Avoid
Cedar or pine shavings

Aromatic oils are toxic to reptiles, and the material holds moisture poorly for a humidity-dependent species while promoting mould.

Avoid
Setup checklist
Tall, front-opening enclosure — minimum 18"×18"×24" for one adultEssential
Crested geckos are arboreal and use height far more than floor space, so a vertically oriented enclosure (like an Exo Terra or similar front-opening terrarium) suits them much better than a long, low tank. Bigger is generally better; 20"×20"×24" or larger is increasingly standard.
Cork bark rounds, flats, and grapevine or manzanita branchesEssential
The single most important furnishing category — this species spends the vast majority of its life climbing and resting off the ground. Fill the enclosure with varied vertical structure rather than floor decor.
No dedicated heat source needed in most homesEssential
Unlike many popular reptile pets, crested geckos generally do best at normal room temperature (72–78°F / 22–26°C) and can suffer heat stress above roughly 82°F (28°C). Most keepers need no basking bulb or heat mat at all — just monitor ambient room temperature, especially in summer.
Fine mesh or well-ventilated screen top/sidesEssential
Good airflow prevents the humidity this species needs from tipping into stagnant, mould-prone dampness. A fully sealed glass enclosure with no ventilation works against the humidity balance rather than helping it.
Digital hygrometerEssential
Target roughly 50–80% humidity, ideally spiking after misting and allowed to drop somewhat before the next misting rather than staying pinned high constantly.
Misting routine (manual or automated) 1–2x dailyEssential
Manual spray bottle misting once or twice a day works for most keepers; a misting system or fogger is popular for larger collections. Good drainage or a false bottom prevents standing water build-up.
Shallow water dishEssential
Most hydration actually comes from misted droplets on leaves and décor rather than the dish, but one should still be available and cleaned regularly.
Low-level UVB (5–6% output)Recommended
Not strictly mandatory the way it is for a basking desert species, but increasingly recommended by experienced keepers and several reptile vets as good practice, positioned to avoid direct high-intensity exposure given this species' more shaded natural habitat.
Digital thermometerRecommended
Confirms ambient enclosure temperature stays within the safe range, particularly important if the room the enclosure is in can get warm in summer.
Feeding ledge or shallow dish mounted mid-heightRecommended
Crested geckos feed at height in the wild — mounting the CGD dish partway up the enclosure rather than on the floor better matches natural feeding behaviour and keeps food away from substrate contamination.
Live or artificial dense foliageOptional
Beyond climbing branches, dense leafy cover gives a naturally shy, mostly nocturnal species places to feel secure during the day.
Bioactive clean-up crew (isopods + springtails)Optional
Pairs well with the coco fibre/moss substrate this species already needs, processing waste in a humid bioactive setup.
Never cohouse crested geckos. They are solitary animals. Two geckos in one enclosure causes chronic stress, competition for resources, and frequently results in injury. Even two females who appear to tolerate each other are under stress that shortens their lives.
