Crested Gecko Care: Complete Guide to Housing, Diet & Handling 2026

Crested geckos are one of the best reptile pets for beginners and experienced keepers alike. Rediscovered in 1994 after being thought extinct, these arboreal geckos from New Caledonia are now one of the most popular pet reptiles in the world — known for their ease of care, docile nature, and stunning variety of colors and patterns called “morphs.”

About the Crested Gecko

The crested gecko (Correlophus ciliatus) is a medium-sized gecko native to southern New Caledonia, a French island territory in the Pacific. Its name comes from the distinctive crests of skin that run from its eyes down its back — giving it an almost dragon-like appearance. Crested geckos are nocturnal and arboreal (tree-dwelling), spending most of their time climbing in the forest canopy.

One of the crested gecko’s most famous traits is its semi-prehensile tail — and its ability to drop that tail (called autotomy) when threatened. Unlike many lizards, crested geckos’ tails do not regenerate. This is perfectly natural and doesn’t affect the gecko’s health or quality of life. “Frogbutt” is the affectionate nickname for tailless crested geckos.

Enclosure Setup & Environment

Crested geckos are arboreal, so they need vertical height more than floor space. For a juvenile (under 25g), start with a 10–20 gallon tank. Adult crested geckos need a minimum of a 20-gallon tall or 29-gallon tall enclosure. Many keepers prefer 40-gallon tall enclosures or commercial bioactive vivariums for enriched environments.

Key enclosure elements:

Screen lid: Essential for ventilation and preventing escapes. Crested geckos are excellent climbers and can squeeze through surprisingly small gaps.
Substrate: Coconut fiber, sphagnum moss, or a bioactive mix (ABG mix) works well. Avoid sand, gravel, or wood chips, which can cause impaction if ingested.
Plants and branches: Cork bark tubes, fake or live plants (pothos, bromeliads, and philodendron are popular), and branches for climbing and hiding. Cover should be dense — crested geckos feel stressed without ample hiding spots.
Misting: Mist the enclosure once or twice daily to maintain humidity of 60–80% and provide drinking water. Allow the enclosure to dry slightly between mistings to prevent mold.

Crested geckos are unusual in that they do not require UVB lighting, though low-level UVB (2.0 or 5.0) is now recommended by many reptile vets for optimal health. They do need a day/night light cycle — 12 hours light, 12 hours dark. Importantly, crested geckos are sensitive to high temperatures: anything above 82°F (28°C) for extended periods can be fatal. They actually thrive at room temperature in most homes.

Diet & Feeding Schedule

Crested geckos are omnivores in the wild, eating insects, nectar, and fruit. In captivity, feeding has been revolutionized by Crested Gecko Diet (CGD) — a complete powdered meal replacement that, when mixed with water, provides all the nutrition a crested gecko needs. Repashy Crested Gecko MRP and Pangea Fruit Mix are the two most popular and trusted brands, both developed with input from professional herpetoculturists.

A standard feeding schedule for crested geckos:

CGD (meal replacement): Offered 3–4 times per week for juveniles; 2–3 times per week for adults. Mix to a smooth consistency (no lumps) and place in a small dish or ledge feeder. Remove any uneaten CGD after 24 hours to prevent bacterial growth.
Live insects: Crickets, black soldier fly larvae, or dubia roaches offered 1–2 times per week, dusted with calcium powder (without D3 for most meals, with D3 twice monthly). Insects should be no larger than the space between the gecko’s eyes.
Fruit purée: Occasional treat (mango, papaya, or commercial fruit baby food without added sugars). Not a dietary staple.

Fresh water should always be available in a shallow dish, in addition to the misting routine.

Handling & Temperament

Crested geckos are generally very tolerant of handling once acclimated — making them ideal for children and adults alike. However, newly acquired geckos need a 2-week settling period with minimal handling to reduce stress.

When handling, use the “hand-walking” technique: let the gecko walk from one hand to the other continuously, rather than gripping it. Keep sessions to 10–15 minutes initially, gradually increasing as the gecko becomes more comfortable. Always wash hands before and after handling. Handle near a surface (such as a bed or couch) so that if the gecko jumps, it won’t fall far.

Crested geckos are nocturnal, so the best handling window is in the evening hours when they are naturally active. Avoid handling during the day when they prefer to rest.

Common Health Issues

Crested geckos are generally robust, but watch for these conditions:

Metabolic Bone Disease (MBD): Caused by insufficient calcium or vitamin D3. Symptoms include soft jaw, rubbery limbs, and inability to climb. Preventable with proper supplementation and low-level UVB lighting.
Respiratory infections: Usually triggered by excessive humidity without adequate ventilation, or temperatures that are too cool. Signs include wheezing, mucus, and open-mouth breathing.
Stuck shed (dysecdysis): Incomplete shedding can constrict toes and cause digit loss. If you notice retained shed, increase humidity and offer a moist hide. Never forcibly pull shed skin.
Cryptosporidium: A parasitic infection causing weight loss and thin appearance (“stick tail” in related gecko species). Requires vet diagnosis and treatment.

Annual vet checkups with a reptile-experienced veterinarian are recommended. Find a reptile vet through the Association of Reptilian and Amphibian Veterinarians (ARAV) directory.

Are crested geckos good pets for beginners?

Yes, crested geckos are widely regarded as one of the best reptile pets for beginners. They do not require specialized UVB lighting (though it’s beneficial), they thrive at room temperature in most homes, they’re docile and tolerant of handling, and they can be fed a complete diet from a commercial powder mix. Their relatively long lifespan of 15–20 years means they’re also a significant long-term commitment.

How often do crested geckos eat?

Juvenile crested geckos should be offered crested gecko diet (CGD) 3–4 nights per week, plus live insects 1–2 times per week. Adult geckos can be fed CGD 2–3 times per week with insects once weekly. Always remove uneaten CGD after 24 hours to prevent bacterial growth. Fresh water should be available at all times.

Do crested geckos need special lighting?

Crested geckos do not strictly require UVB lighting to survive, unlike many other reptiles — but low-level UVB (2.0 or 5.0) is now recommended by reptile veterinarians for optimal health, bone density, and immune function. They do need a 12-hour day/night cycle. Avoid exposing them to direct sunlight or temperatures above 82°F, which can be fatal.

Can crested geckos live together?

Female crested geckos can sometimes be housed together in a sufficiently large enclosure (40+ gallons), though cohabitation always carries risks of stress and injury. Two males should never be housed together, as they will fight. A male-female pair will breed continuously, which is stressful for the female. For beginners, housing geckos separately is strongly recommended.

Why did my crested gecko’s tail fall off?

Crested geckos can voluntarily drop their tails (a defense mechanism called autotomy) when they feel threatened, stressed, or are handled roughly. Unlike many lizards, crested geckos do not regenerate their tails — the loss is permanent. This is medically harmless and doesn’t affect their quality of life. To prevent tail loss, handle your gecko gently, avoid gripping the tail, and ensure they have a secure, low-stress environment.
