Crested Gecko Care Guide

The crested gecko is endemic to the South Province of New Caledonia — a semi-tropical archipelago between Fiji and Australia in the South Pacific. Wild populations occupy three disjunct areas on the main island of Grande Terre and the Isle of Pines, inhabiting subtropical rainforest from sea level up to approximately 1,000 metres elevation.

First described in 1866, the species was subsequently believed to be extinct for over a century before its dramatic rediscovery in 1994 following a tropical storm that pushed researchers into previously unexplored forest. This rediscovery launched one of the most successful captive-breeding stories in modern herpetoculture.

New Caledonia experiences a warm, humid wet season (November–March, peaking around 86°F / 30°C) and a cooler, drier season (June–August, around 72°F / 22°C). Annual rainfall reaches 120 inches. Understanding these seasonal rhythms matters in captivity — the crested gecko is adapted to a moderate temperature band and is acutely sensitive to overheating.

Crested geckos are arboreal — they climb, hang upside-down, and prefer height over floor space. Vertical enclosures are essential.

Provide ample climbing structure: cork bark rounds and flats, branches (grape wood, bamboo), artificial plants for cover. Crested geckos feel exposed without sufficient foliage — a bare enclosure causes chronic stress. A sleeping spot at height (cork tube, silk leaf hammock) is appreciated and regularly used.

Crested geckos are highly sensitive to heat. Overheating is the most common cause of death in captive crested geckos.

Most keepers in temperate climates do not need supplemental heating — a well-insulated home at 70–75°F is ideal. If temperatures drop below 65°F consistently, a low-wattage ceramic heat emitter on a thermostat can be used.

Crested geckos require a misting cycle that replicates the wet-dry rhythm of their native New Caledonia.

Misting schedule: Mist the enclosure heavily once or twice daily (morning and/or evening). Allow it to dry out mostly between sessions — sustained dampness causes bacterial and fungal issues. The enclosure should be humid after misting (80%+ briefly) and drop to 50–60% before the next misting.

A live planted bioactive setup with good drainage naturally maintains appropriate humidity and requires less active management. At minimum, substrate should not be bone dry — a light bottom layer moisture is appropriate.

Crested geckos are omnivores, and feeding them in captivity is unusually simple thanks to commercially formulated Complete Gecko Diets (CGD).

Pangea Fruit Mix, Repashy Crested Gecko Diet, or Arcadia Insect and Fruit are the most widely used and nutritionally validated options. CGD alone can form a complete diet — no supplementation required when using a reputable brand.

Insect supplementation: Offering live insects (crickets, Dubia roaches, waxworms) 2–3 times per month increases feeding engagement, stimulates natural hunting behaviour, and improves breeding condition. Dust insects lightly with calcium + D3 powder.

Fruit: Small amounts of mashed banana, mango, or papaya can be offered as an occasional treat. Avoid citrus and high-oxalate fruits.

Feeding schedule: Offer CGD 3–4× per week. Remove uneaten CGD after 24–36 hours to prevent fermentation.

Metabolic Bone Disease (MBD): Soft or deformed jaw, limb weakness, difficulty climbing. Caused by calcium/D3 deficiency. Ensure CGD includes calcium and D3, or dust feeder insects. Adding low-level UVB lighting significantly reduces MBD risk.

Tail loss (autotomy): Crested geckos will voluntarily drop their tail when threatened. Unlike many other geckos, crested geckos do not regenerate lost tails — a "frog butt" gecko is permanent and otherwise healthy. The drop site heals cleanly.

Stuck shed: Retained skin around the toes is the most common shed issue. A 15-minute warm water soak usually resolves mild retention. Check toes after every shed — retained constricting skin on toes will cut off circulation and cause digit loss if left for days.

Overheating: Lethargy, loss of grip, open-mouth breathing in a warm enclosure. Move the gecko to a cooler location immediately. Provide fresh water. Most geckos recover fully from brief heat exposure.
