Crested Gecko Care: A Complete Beginner Hub

Quick answer

Crested Gecko Care: A Complete Beginner Hub

Crested geckos are a great beginner reptile: they stay small, tolerate normal room temperatures, and thrive on a powdered complete diet you just mix with water. Give a single adult a tall, planted terrarium of at least 45 x 45 x 60 cm, keep humidity moderate with daily misting, and handle gently in short sessions.

• Adult size is about 10-12 cm nose to vent and they can live 15-20 years.
• They are arboreal and nocturnal, so vertical space matters more than floor area.
• A commercial complete diet removes almost all guesswork about nutrition.
• They do not need a hot basking lamp the way desert lizards do.
• Never house two males together; they will fight.

Housing and space

Because crested geckos climb, choose a tall front-opening terrarium. One adult needs at least 45 x 45 x 60 cm; bigger is better and taller is best. Fill it with cork bark, sturdy branches, and broad-leaved plants (live pothos or sturdy artificial foliage) so your gecko can climb and hide at several heights. A hatchling can start in a smaller tub so it can find food easily, then move up.

Crested geckos are arboreal, so height and climbing branches matter more than floor space.

Temperature, humidity and lighting

Crested geckos are comfortable at 22-26C, the range of a typical living room. Avoid heat above 28-29C, which is genuinely dangerous for them. In a warm, humid climate you often need no extra heat at all; if your room dips cool at night a low-wattage panel with a thermostat is enough. Mist once or twice daily so humidity rises toward 70-80% then dries back toward 50%, giving a wet-then-dry cycle rather than a permanent swamp. A low-output UVB tube is optional but beneficial.

Feeding

The simplest safe diet is a commercial powdered complete crested gecko diet mixed with water to a ketchup consistency, offered in a small dish every other evening. You can add appropriately sized, gut-loaded and calcium-dusted insects once or twice a week as enrichment. Fresh water should always be available in a shallow dish.

A commercial complete diet mixed with water covers most of a crested gecko's nutrition.

Handling and temperament

Crested geckos tolerate gentle handling but are fast and can jump. Let a new gecko settle for a week or two before handling, then keep sessions to a few minutes low over a soft surface. Support the body rather than gripping. Never grab or restrain by the tail: crested geckos drop their tails when frightened and, unlike many geckos, do not grow them back. A tailless crestie is otherwise perfectly healthy.

Health and warning signs

A healthy crested gecko is alert at night, has a rounded tail base, clear eyes, and clean skin. Common beginner problems come from heat that is too high, chronic low humidity causing stuck shed on the toes, or metabolic bone disease from poor diet.

Living context by region

This guide is written for multi-region English readers (US/UK/AU/NZ/CA/EU and more). Where climate, products, or vet access differ, prefer local veterinary advice and local product labels. Use metric first; keep °F/lb in mind for North American homes.

When to call your vet

• Signs are getting worse over hours, not better

• Pain, persistent vomiting/diarrhea, or neurological signs

• You needed force or guesswork to keep going at home

Common mistakes

• Waiting because the animal 'still looks okay' while prey species hide pain

• Changing five variables at once so you cannot tell what helped

• Copying drug doses from social media

• Skipping species-appropriate husbandry while buying more gadgets
