Crested Gecko Care Guide (2026)

Crested geckos are one of the most popular pet reptiles in the world — easy to care for, visually striking, and available in an enormous range of morphs. This guide covers everything you need to keep a crested gecko healthy and thriving.

Overview

Crested geckos (Correlophus ciliatus) are native to New Caledonia, a group of islands in the South Pacific. Once thought extinct, they were rediscovered in 1994 and quickly became one of the most popular reptiles in the hobby. They're arboreal, nocturnal, and uniquely capable of dropping and not regrowing their tails — a trait that surprises many new keepers.

Lifespan

Crested geckos commonly live 15–20 years in captivity with proper care. See our full guide: Crested Gecko Lifespan.

Size

Adults typically reach 6–8 inches in total length and weigh around 35–60 grams. Their compact size makes them well-suited to apartment living and smaller spaces.

Temperament

Crested geckos are generally calm and tolerate handling well once acclimated. They can be quick and jumpy, especially as juveniles, so handling sessions should be calm and low to the ground. Most settle into a predictable routine and become quite comfortable with regular interaction. See our full guide: Crested Gecko Handling Guide.

Beginner Friendly?

Yes — crested geckos are one of the top beginner recommendations. They thrive at room temperature in many climates, don't require UVB (though it's beneficial), and can be fed a commercially prepared meal replacement powder as their primary diet. Their main requirements are correct humidity, a tall enclosure, and temperatures that don't exceed 80–82°F.

Enclosure

Crested geckos are arboreal and need vertical space. A minimum of an 18" x 18" x 24" enclosure is recommended for a single adult, with 18" x 18" x 36" or larger being ideal. Glass or PVC front-opening terrariums are the most common choice. Screen enclosures can work in warm, humid climates but often make humidity more difficult to maintain.

Heating

Crested geckos don't require supplemental heating in most homes. They thrive at 72–78°F and should never be exposed to temperatures above 80–82°F for extended periods. The most common beginner mistake is overheating, not underheating. If your home drops below 65°F at night, a low-wattage ceramic heat emitter on a thermostat may be needed.

  • Daytime: 72–78°F
  • Nighttime: No lower than 65°F
  • Maximum: 80–82°F

Lighting

Crested geckos can be kept successfully without UVB, but low-level UVB is increasingly recommended as part of a natural lighting setup. Maintain a consistent 12-hour light/dark cycle, adjusting slightly with the seasons if possible.

Humidity

Crested geckos need a wet/dry humidity cycle rather than constant high humidity. Mist the enclosure heavily once or twice daily to raise humidity to 80–90%, then allow it to drop back to 50–70% before the next misting. Constant high humidity without drying periods can cause respiratory infections.

Substrate

Crested geckos benefit from substrates that hold some moisture and support live plants in bioactive setups. Popular options include coconut fiber, bioactive mixes, and sphagnum moss. Paper towels are suitable for hatchlings or quarantine setups only.

Feeding

Crested geckos are omnivores. In captivity, most keepers use a meal replacement powder (MRP/CGD) such as Repashy or Pangea as the dietary staple — simply mix with water and offer in a small dish. Insects can be offered as enrichment and supplemental protein 1–2 times per week. Dust live insects with calcium and a multivitamin before feeding.

Hides & Enrichment

As arboreal geckos, crested geckos need vertical enrichment more than floor hides. Provide plenty of climbing branches, cork bark tubes, and live or artificial plants. A cork tube or hollow branch at mid-height makes an excellent daytime retreat.

Health Problems

Common crested gecko health issues to watch for:

  • Respiratory infection — wheezing, nasal discharge, open-mouth breathing; often linked to constantly damp conditions or poor ventilation
  • Stuck shed — retained skin on toes or eyes; caused by insufficient humidity; toes require prompt attention
  • Feeding refusal — common in new geckos, during shed, or with CGD brand changes; check husbandry first
  • Tail drop (autotomy) — a normal stress response; crested gecko tails do not regrow
  • Floppy tail syndrome — associated with prolonged upside-down hanging in sparsely furnished enclosures
  • Metabolic bone disease (MBD) — caused by calcium or D3 deficiency; rubbery limbs, difficulty moving

FAQ

Do crested geckos need heat lamps?

Usually not. Most homes stay within their preferred temperature range naturally. The bigger concern is keeping them cool enough — temperatures above 80–82°F are dangerous. See our full guide: Crested Gecko Temperature & Humidity Guide.

Can crested geckos live together?

Males should never be housed together. A male and female will breed, which is stressful for the female. Two females may cohabitate in a large enough enclosure, but individual housing is always the safest option.

Why did my crested gecko drop its tail?

Tail drop is a defensive stress response. Unlike most geckos, crested geckos do not regrow their tails. A tailless crested gecko is perfectly healthy. See our full guide: Why Did My Crested Gecko Drop Its Tail?

How often should I mist my crested gecko's enclosure?

Once or twice daily is typical. The goal is a wet/dry cycle — mist heavily, then let the enclosure dry before misting again. See our full guide: Crested Gecko Temperature & Humidity Guide.

How long do crested geckos live?

15–20 years with proper care. See our full guide: Crested Gecko Lifespan.
