Crested Gecko Care Guide: Habitat, Diet & Handling

Crested geckos (Correlophus ciliatus) are climbing geckos. The eyelash-like crests above the eyes and the two rows of crests along the back, both visible in the photograph above, are the features the species is named for. Adults reach 8–10 inches including the tail and live 15–20 years in captivity — the same lifespan band as leopard geckos, with entirely different daily needs.

The most common mistake with this species is setting it up like a leopard gecko: a horizontal enclosure, a hot spot, and dry air. Crested geckos need height to climb, cooler temperatures than most keepers expect, and humidity that cycles up and down rather than staying at one level. Get the orientation of the enclosure right — tall, not long — and the rest of the guide follows from it.

A vertical enclosure: at least 18×18×24 inches for an adult, with 18×18×36 inches as the recommended upgrade. The numbers read differently from a leopard gecko enclosure on purpose — the third number is the height, and it is the number that matters most. A crested gecko spends its time on branches, leaves, and the enclosure walls, using the full height of the space, and a long, low enclosure wastes the dimension the animal actually uses.

Height alone is not enough. The enclosure needs usable height: branches and foliage at several levels, so the animal can climb, rest, and choose where to spend time, rather than one perch at the top and empty space below. Think in layers — low cover, middle branches, and upper resting spots — and check that the animal can move between them without dropping to the floor.

Juveniles can start in a smaller enclosure and move up as they grow, but the adult enclosure is the size to plan for. An enclosure that is too large for a very small juvenile can make finding food harder; an enclosure that stays too small for an adult removes the climbing space the species is built for. Size the enclosure to the animal in it, and upgrade on schedule.

Build the enclosure around climbing and cover. Sturdy branches at several heights, broad-leaved foliage — live or artificial — for hiding and resting, and a substrate that holds some moisture without staying sodden. The animal should be able to move through the enclosure under cover for most of its route, not cross open space to reach every perch.

Place food and water where the animal can reach them from a branch. Crested geckos feed in elevated dishes, and a dish on the floor of a tall enclosure is easy to overlook and hard for the animal to use comfortably. Keep the feeding spot consistent so the animal learns where food appears, and check it the morning after feeding — an untouched dish and an empty dish tell different stories, and both matter.

Ventilation matters as much as misting. Humidity must be able to fall between mistings, and an enclosure that stays wet all day is not the same as an enclosure held at 50–70%. If condensation never clears and the substrate stays wet, increase airflow and reduce misting before changing anything else.

Day temperatures of 72–80°F (22–27°C) and night temperatures of 65–72°F (18–22°C). That range sits inside normal indoor temperatures in many homes, which is why many keepers need no additional heating at all. The danger with this species is overheating, not cold: temperatures above the day range stress crested geckos quickly, and a heat lamp set up as if for a desert species can push the enclosure past what the animal can tolerate.

Measure temperature where the animal rests, at the top of the enclosure as well as the bottom — warm air rises, and the upper levels where a crested gecko spends its time can be warmer than the floor. If the room itself runs warm, choose the coolest suitable spot in the room for the enclosure before adding any equipment.

Humidity is 50–70%, with a cycle: a peak after misting, then a fall before the next misting. The cycle is the point. Constantly saturated air and constantly dry air are both wrong, even though their averages might both read inside the range. Mist in the evening, when the animal becomes active, and let the enclosure dry back between mistings. A hygrometer placed at mid-height, where the animal rests, tells you more than one placed at the substrate.

The staple is a powdered crested gecko diet (CGD) — a prepared fruit-based powder mixed with water — offered every other day. Live insects are a supplement, once or twice a week, not the main diet. That balance is the opposite of the leopard gecko routine, and it is the single most useful distinction between the two species’ feeding guides.

Offer the powdered diet fresh each time, in a shallow elevated dish, and remove the old dish before offering a new one. Prepared diet left in the enclosure dries out and loses appeal, and an animal that stops eating is often an animal that is being offered stale food in the wrong place. Keep a note of whether the dish shows feeding marks — lick marks in the smooth surface — so a change in appetite is noticed in days, not weeks.

Live insects, when offered, should be appropriately sized and gut-loaded. They add variety and hunting behaviour, and they are a useful way to check that the animal is active and feeding well. They do not replace the powdered diet: a crested gecko fed only on insects is missing the balanced nutrition the prepared diet is formulated to provide.

Most crested geckos at normal room temperature do not need a heat lamp. If the room regularly falls below the night range of 65–72°F (18–22°C), low-level supplementary heating may be needed — but it should be set up to hold the enclosure inside the range, not to create a hot spot of the kind a leopard gecko uses. If in doubt, measure the enclosure for a week before buying heating equipment.

Low-intensity UVB (Zone 1) is recommended but not compulsory, and keeping at room temperature without UVB is also workable. As with leopard geckos, the decision is a package: UVB, diet, and supplementation together. A crested gecko on a complete powdered diet, kept inside the temperature and humidity ranges, is not in the same position as an animal missing one of those pieces.

Watch for the combination that causes harm: a heat lamp added “just in case” in an already warm room, in an enclosure with poor ventilation. That combination raises temperature, dries the air, and removes the cool, humid resting spots the animal uses. When heat is added, it should be controlled, measured, and removable — and the animal should always be able to move away from it.

Handle gently and close to a surface, letting the gecko walk from hand to hand. Crested geckos can jump, and they do — often without warning and further than expected. Handle over a bed, sofa, or other soft surface, in a closed room, until you know the individual animal’s behaviour. A fall from standing height onto a hard floor is a real injury risk for a small climbing animal.

Never hold a crested gecko by the tail. Like many geckos, crested geckos can drop their tails, and in this species the tail does not regrow — an animal that loses its tail keeps the change for life. Support the body, avoid sudden grabs, and if the animal is moving fast, let it move onto a branch or back into the enclosure rather than tightening your hold.

New animals need a settling period before handling becomes routine. Let the gecko eat from its dish on schedule and use the enclosure’s cover confidently first. Short, calm sessions build trust faster than long sessions that end with the animal trying to escape, and handling in the evening — when the animal is naturally active — is usually easier than handling during the day, when it would rather rest.

This section covers recognition and prevention only. It does not diagnose or treat. If a crested gecko stops eating, loses weight, or shows any of the signs below, see a qualified exotics veterinarian.

Check temperature and humidity first. An enclosure running above 80°F (27°C), or humidity stuck at one extreme, will change appetite and behaviour before any illness does. Check that the powdered diet is fresh, in the right place, and showing feeding marks. Then check the animal itself: weight, tail thickness, skin condition, and shedding.

Signs worth a prompt veterinary visit include continued weight loss, a tail that is visibly thinning, repeated difficulty shedding — especially shed retained on toes or around the tail tip — lethargy that does not lift once temperature and humidity are corrected, and any injury, swelling, or discharge. Shed retained on toes can restrict blood flow if left, so it is worth checking toes and tail tip after every shed, gently, and seeking help rather than pulling shed off by force.

Keep the same simple record as for any reptile: feeding dates, shed dates, and weight where possible. With crested geckos, add a note of whether the dish showed feeding marks. A record turns a vague “it hasn’t eaten much lately” into a date the problem started, which is what a veterinarian needs to work with.
