Chapter 1 of 9 · Crested Gecko Care Guide
Start Here: Is a Crested Gecko Right for You?
Disclaimer: I'm not a veterinarian and I don't hold a degree in animal science or animal care. This guide is compiled from the published sources listed in every chapter. For a sick animal, a reptile vet is the authority.
The short version
- Crested geckos are small, gentle, night-active climbers from New Caledonia that live 15–20 years [1][2].
- They do best at normal room temperature. Too much heat is a bigger danger than cold [2][4].
- A tall enclosure, evening misting, and a complete powdered gecko diet cover most of what they need [1][3].
- Their tail can drop off if it is grabbed or pinched, or if the gecko is startled, and it never grows back. That is not a medical emergency [5].
- Like all reptiles, they can carry Salmonella, so hand-washing after every contact is a must [6].
Meet the crested gecko
The crested gecko (Correlophus ciliatus) comes from the rainforests of New Caledonia, a group of islands in the South Pacific. It was once thought to be extinct, was rediscovered in 1994, and is now one of the most common captive-bred lizards in the US [1][2].
Cresties live up in the trees. They climb glass with sticky toe pads, lick water droplets off leaves, and eat fruit, nectar and insects. They are most active at dusk and through the night, so evening is when you will see yours exploring and eating [1].
Adults reach about 8 in (20 cm) long and usually weigh about 35 grams or more. They are adults at around 15–18 months [1][2].
Is this the right pet for you?
A crested gecko is often a great first reptile. Here is why, and what to think about before you bring one home.
Good reasons to choose a crested gecko
- No hot basking spot needed. Most homes are already the right temperature for most of the year [1][2].
- Easy feeding. A complete powdered diet, mixed with water, covers most nutrition. Live insects are an optional extra, not a daily chore [3].
- Calm and quiet. Bites are rare and harmless, and they make no noise worth mentioning [2].
- Small footprint. One adult fits in a tall enclosure that takes up about as much floor space as a nightstand [1][2].
Things to think about first
- It is a long commitment. With good care, a crested gecko can live 15–20 years [1][2].
- Heat can kill. If your home regularly gets above about 82°F (28°C) in summer and you cannot cool one room, this may not be the right species for you [2][4].
- It is a "watch me" pet more than a cuddly one. Short handling sessions are fine, but they jump and do not like being held for long [3].
- The tail is fragile. Grabbing the tail can make it drop, and it will not grow back [5].
- Hygiene matters. Wash your hands with soap and water after touching your crested gecko, its enclosure or anything in it. The CDC says children under 5 should not touch reptiles, and reptiles are not recommended for homes with children under 5, adults 65 and older, or people with weakened immune systems [6].
Crested gecko at a glance
| Item | What to know |
|---|---|
| Origin | New Caledonia; tree-dwelling, active at dusk and night [1] |
| Adult size | About 8 in (20 cm) long; about 35 grams or more [1][2] |
| Lifespan | 15–20 years with good care [1][2] |
| Adult enclosure | At least 18×18×24 in (45×45×60 cm), front-opening glass [1]. Some guides call for 18×18×36 in (45×45×90 cm) or 24×24×24 in (60×60×60 cm) [2][3]; taller is better |
| Temperature | 72–78°F (22–26°C) by day; 65–72°F (18–22°C) at night [1][3] |
| Humidity | 60–80%, with heavy evening misting and a drier day [1][3] |
| Lighting | Day/night light cycle; low-level UVB is optional but helpful [1][3] |
| Diet | Complete powdered gecko diet as the staple; insects as an extra [3] |
| Handling | Wait 2–4 weeks after bringing it home, then start with short sessions [2][3] |
| Housing | One gecko per enclosure is safest. Some breeders keep one male with several females [2]; two males should never share an enclosure |
What to do next
Read the chapters in order before your gecko comes home. Set up the enclosure first and check temperatures for a few days, so your new gecko moves into a home that is already stable.
- Housing and environment covers enclosure size, heat, humidity, lighting and substrate.
- Feeding covers powdered diets, insects, fruit and calcium.
- Handling and behavior covers settling in, tail loss and why one gecko per enclosure is best.
- Health covers quarantine, common problems and when to see a vet.
- Breeding and Genetics and morphs are for keepers who want to go further.
- The Owner checklist is a one-page sheet you can print and keep by the enclosure.
In New York State, keeping a captive-bred crested gecko generally does not require a permit. Rules can change, so check with the NYS Department of Environmental Conservation if you are unsure.
