Crested Gecko Care: A Complete Beginner Hub
Crested geckos are one of the easiest reptiles for first-time keepers. This hub covers the tall terrarium they need, comfortable room-temperature husbandry, an easy powdered diet, safe handling, and the health signs that mean it is time to call an exotics vet.
Quick answer
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.

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.
Quick FAQs
Do crested geckos need UVB? They can live without it on a complete diet, but a low-level UVB tube supports better bone health and is a sensible upgrade.
Can I keep two together? Two females may cohabit in a large tank, but never two males, and never a male-female pair unless you intend to breed. When unsure, house singly.
Why did my gecko drop its tail? Fear, a fall, or being grabbed by the tail. It is dramatic but not an emergency; keep the area clean and the gecko will heal, though the tail will not regrow.
How long do crested geckos live? With good care, commonly 15-20 years, so this is a long-term commitment.
