Crested Gecko Care: A Complete Beginner's Guide

Crested geckos are one of the most forgiving reptiles you can keep. They thrive at room temperature, eat a commercially available powdered diet, and are small enough to house comfortably in a living room. If you're new to reptiles, they're a genuinely good starting point, not because they're maintenance-free, but because their care requirements are consistent and well understood.

This guide covers everything you need to set up correctly the first time.

Species Overview

Crested geckos (Correlophus ciliatus) are native to New Caledonia, a group of islands in the South Pacific. They were thought to be extinct until rediscovered in 1994 and have since become one of the most popular pet lizards in the world.

Adults reach 7 to 9 inches (18 to 23 cm) from snout to tail tip and typically weigh 35 to 55 grams. A healthy, well-kept crested gecko can live 15 to 20 years, so this is a long commitment.

One trait worth knowing upfront: crested geckos can drop their tails as a defense mechanism (called autotomy), and unlike many lizards, they do not regenerate them. A tailless gecko is completely healthy and normal, breeders call them "frogbutts", but it's something to be aware of during handling, especially early on when your gecko is still getting used to you.

Enclosure Setup

Crested geckos are arboreal, meaning they live in trees and prefer to climb rather than burrow. Vertical space matters more than floor space.

The minimum enclosure size for a single adult is 18 x 18 x 24 inches (45 x 45 x 60 cm). This is the standard "tall" terrarium format sold by most reptile brands. Juveniles can start in something smaller, but adults need the full height. Screen or mesh-sided enclosures improve airflow and make maintaining humidity easier.

Inside the enclosure, provide:

• Climbing branches and cork bark, diagonal and horizontal pieces let your gecko move naturally
• Live or artificial plants, pothos, philodendron, and bromeliads all work well for live setups; high-quality silk or plastic plants are fine otherwise
• Hides, at least two: one in the upper part of the enclosure (warm side) and one lower (cool side)
• A water dish, even though geckos drink from misted droplets, a shallow dish provides a backup water source

Bioactive setups with a living substrate (organic topsoil, peat, and coco fiber layered with springtails and isopods) are popular for crested geckos and make humidity management easier. A paper towel or reptile carpet substrate also works fine if you want something simpler to clean.

Temperature Requirements

This is where crested geckos stand apart from most reptiles: they don't need a basking lamp or supplemental heat if your home stays within a reasonable range.

The ideal temperature band is 72 to 78°F (22 to 26°C), which matches typical indoor temperatures in most households. They can tolerate brief dips to the low 60s°F (around 16°C) without harm, but extended cold will suppress their immune system and slow digestion.

The critical limit on the other side is heat. Temperatures above 82°F (28°C) cause significant stress. Above 85°F (29°C), crested geckos can die quickly. If your home gets hot in summer, you need a plan, a small air conditioner, a basement location, or a cooling fan positioned to circulate air around (not directly into) the enclosure.

Do not use heat mats under glass or plastic enclosures without a thermostat, and avoid incandescent basking bulbs unless you're in a genuinely cold room and using a thermostat to regulate output. Most keepers in temperate climates need no supplemental heat at all.

Humidity and Misting

Crested geckos need 60 to 80% relative humidity. Consistent humidity prevents shedding problems and keeps their respiratory tract healthy.

The standard approach is a "wet/dry cycle": mist the enclosure once or twice daily (morning and evening works well), allowing it to partially dry between sessions. This mimics the natural cycle of rain followed by drying in their native habitat.

Use a digital hygrometer to monitor levels. During a shed, you can mist more frequently to keep the skin soft and loosening evenly.

Signs of humidity that's consistently too low: retained shed, especially around the toes, and skin that looks dull or tight. Signs of too much humidity with no drying period: mold growth on substrate, respiratory wheezing, and scale infections. The wet/dry cycle prevents both.

An automated misting system (like a Mistking or Exo Terra fogger) can simplify this if you have an inconsistent schedule.

Diet and Feeding

Crested geckos are one of the few reptiles that can eat a commercially formulated, nutritionally complete powder diet as their primary food source. Brands like Repashy, Pangea, and Black Panther Zoological have published feeding studies behind their formulas, and long-term captive populations have done well on them.

Mix the powder with water to a pudding consistency and offer it in a small dish 3 to 4 times per week. Remove uneaten food within 24 hours to prevent bacterial growth.

Live insects make a good supplement. Crickets and dubia roaches in appropriate sizes (no wider than the space between the gecko's eyes) can be offered once or twice a week, dusted with calcium + D3 powder. Insects add enrichment and protein, especially useful for juveniles and breeding females.

Avoid feeding wild-caught insects (pesticide risk) and citrus fruit (too acidic). Waxworms and other fatty treats should be rare.

Fresh water should be available at all times. Crested geckos drink water droplets off leaves after misting, but a small water dish provides security between misting sessions.

Handling and Temperament

Crested geckos are generally calm once acclimated, but they're fast and can jump. New geckos should be given one to two weeks to settle in before handling begins.

Start with brief sessions, five minutes or less, and let the gecko walk from hand to hand rather than gripping it. Hand-walking keeps them moving and engaged without feeling restrained. Build up time gradually over several weeks.

Most crested geckos become quite comfortable with regular handling. A few individuals remain flighty regardless of how much time you put in. Temperament varies by individual, not just by species.

If your gecko drops its tail during handling, stay calm. Put the gecko back in the enclosure, remove the still-moving tail (it can startle the gecko if it sees it), and check the wound site. Tail drops heal cleanly in most cases. Keep the substrate clean and watch for signs of infection. No regrowth will occur.

Never grab a crested gecko by the tail.

Care Summary

Parameter	Value
Adult size	7 to 9 inches (18 to 23 cm)
Lifespan	15 to 20 years
Enclosure (adult)	18 x 18 x 24 in (45 x 45 x 60 cm), tall/arboreal
Temperature	72 to 78°F (22 to 26°C); max 82°F (28°C)
Humidity	60 to 80%; wet/dry misting cycle
Diet	CGD powder diet + occasional dusted insects
UVB lighting	Optional but beneficial; low-output 2.0 or 5.0
Handling	After 1 to 2 week acclimation; 5 min to start

A note on UVB: crested geckos are crepuscular (most active at dusk and dawn) and were traditionally kept without UVB. More recent research suggests low-level UVB helps with calcium metabolism and overall health. A T5 HO 5.0 or Arcadia 6% bulb on a 10- to 12-hour cycle is a good addition if you want to optimize the setup, but it is not a requirement the way it is for bearded dragons.

Finding a Vet

Crested geckos are exotic animals. Not every veterinarian has reptile experience. Find an exotics vet in your area before your gecko shows any signs of illness, it's much easier to locate a good practice when you're not in a panic.

Common health issues in crested geckos include retained shed, metabolic bone disease (usually from calcium deficiency), parasites in wild-caught animals, and respiratory infections from chronic humidity imbalance. All of these are treatable when caught early by a vet who knows reptiles.

Frequently Asked Questions

Do crested geckos need a heat lamp?

Most do not. If your home stays between 72 and 78°F (22 to 26°C), no supplemental heat is needed. If your home drops below 65°F (18°C) regularly, a low-wattage ceramic heat emitter on a thermostat can help. Heat lamps that raise temperatures above 82°F (28°C) are harmful.

How often should I feed my crested gecko?

Offer the CGD powder diet three to four times per week, removing uneaten portions within 24 hours. Live insects can be added once or twice a week as a supplement. Juveniles eat more frequently than adults and grow quickly in their first year.

Why did my crested gecko drop its tail?

Tail drops happen when a gecko feels threatened or grabbed incorrectly. It is a natural defense response. The wound heals on its own, and the gecko will live a completely normal life without the tail. Unlike many lizard species, crested geckos do not regenerate lost tails.

Can I keep two crested geckos together?

Two females can sometimes cohabitate in a large enough enclosure, but cohabitation carries real risks: competition for resources, stress, and injury. Males should never be housed together. A male-female pair will breed continuously, which is taxing on the female. For most beginners, one gecko per enclosure is the right setup.

How do I know if my crested gecko is healthy?

A healthy crested gecko is alert at night (they're most active after dark), has clear eyes, smooth skin after a completed shed, and good muscle tone. It should eat consistently and maintain or gain weight over time. A kitchen scale accurate to 1 gram is a simple way to track weight monthly. Sudden weight loss, lethargy, labored breathing, or swollen limbs are all reasons to contact an exotics vet.
