Crested Gecko Care: Setup, Temperatures and Diet
Is a Crested Gecko the Right Pet for You?
Crested geckos are a good first reptile for many people. They are quiet, don't need live insects every day, and are happy at temperatures most homes already have. They are also active at dusk and at night, so the best show starts when you're winding down.
They are not cuddly pets. Short, gentle handling is fine for most, but they're happiest watched, not held. And at 15–20 years, they're a longer commitment than many dogs.
Housing: Build Up, Not Out
In the wild they live in trees, so height matters more than floor space. A commonly recommended minimum for one adult is 18 × 18 × 24 inches (45 × 45 × 60 cm), and bigger is better. Front-opening glass or PVC enclosures with mesh ventilation work well.
- Climbing: cork bark tubes and branches running in every direction, from floor to ceiling.
- Cover: lots of leaves, live or artificial, so the gecko can hide anywhere at any height.
- Floor: a moisture-holding, natural substrate, or paper towels during quarantine.
- Ledges: magnetic feeding ledges up high, because crested geckos rarely come to the floor to eat.
Our guides to terrariums and enclosures and substrate and decor go into the options.
Heat, Light and Humidity
Temperature. Aim for a warmer area of about 75–80°F (24–27°C) and a cooler area of 70–75°F (21–24°C). Many homes are in that range already. If yours runs cooler, add a low-output heat source on a thermostat, mounted above or outside the mesh, never a mat stuck to the glass. Crested geckos handle heat worse than cold, so a room that gets hot in summer needs a plan, such as moving the enclosure or cooling the room. A natural drop at night is fine.
Light and UVB. Give a regular day and night cycle. Many experienced keepers now provide low-level UVB, aiming for a UV index of about 1.0–2.0 near the top of the enclosure, with plenty of leafy shade lower down so the gecko can choose. See UVB lighting explained.
Humidity. Mist so humidity rises to about 80% in the evening and falls toward 60% before the next misting. Letting it dry out between mistings matters, because an enclosure that stays wet all the time breeds mold.
Measure, don't guess. A digital thermometer and hygrometer with probes, and a thermostat on any heat source, are the most useful equipment you can buy. These are typical ranges from keeper care sheets; check with your vet or a specialist keeper for your own setup.

Start with a tall, front-opening enclosure. Add a digital thermometer and hygrometer so you know the real numbers, and a thermostat if you use any heat. A low-output UVB lamp and fixture covers the light. Cork bark and vines give climbing routes, and a complete crested gecko diet plus a feeding ledge handles meals. A fine mist sprayer takes care of the evening humidity boost.
Diet and Feeding
Crested geckos eat fruit, nectar and insects in the wild. In captivity, a complete powdered crested gecko diet, mixed with water as the label says, makes a good main food. Check the label says it is made for crested geckos.
Small live insects, sized no bigger than the space between the gecko's eyes and dusted with a reptile calcium powder, add variety and exercise. Fresh water in a shallow dish, and the droplets from misting, keep it hydrated. Our reptile food page compares the options.
Handling, Company and That Tail
Give a new gecko a couple of weeks to settle before handling. Then keep sessions short, low down and calm, and let the gecko walk from hand to hand. They jump, so sit on the floor at first.
A frightened crested gecko can drop its tail, and unlike many lizards it doesn't grow back. Tailless adults live normal lives, but gentle handling keeps the tail on.
Keep one gecko per enclosure. Males fight, and a pair will breed. Crested geckos don't need company.
Health: Preventive Care
Find a vet who sees reptiles before you bring a gecko home; many practices don't. A check-up after you buy, correct temperatures and humidity, a calcium-dusted insect now and then, and a clean enclosure prevent most problems.
Reptiles can carry salmonella without looking ill. Wash your hands after handling your gecko or anything in its enclosure, and supervise young children, as public health agencies such as the US CDC advise.
Frequently Asked Questions
Heat, light and that tail come up most.
Do crested geckos need a heat lamp?
Often not, if your room already stays within about 70–80°F (21–27°C). In a cooler room, add a low-wattage heat source on a thermostat. Too much heat is a bigger risk for this species than too little, so measure before you buy.
Do crested geckos need UVB?
They can live without it, but many experienced keepers now provide low-level UVB, a UV index of about 1.0–2.0 near the top of the enclosure, with plenty of shade lower down. Ask a reptile vet or specialist keeper which lamp suits your setup.
How big a tank does a crested gecko need?
A common minimum for one adult is 18 × 18 × 24 inches (45 × 45 × 60 cm), taller than it is wide. Bigger is better, as long as it's well planted with plenty of cover.
Can two crested geckos live together?
One per enclosure is the safe default. Males fight, and a male and female will breed. Crested geckos don't get lonely.
Will my crested gecko's tail grow back?
No. A crested gecko can drop its tail when frightened, and unlike many lizards it doesn't regrow it. Tailless adults live normal lives, but gentle handling keeps the tail where it belongs.
How long do crested geckos live?
Around 15–20 years with good care, so plan for a long commitment.
