The crested gecko (Correlophus ciliatus) was believed extinct until its rediscovery in New Caledonia in 1994. Within a decade it became one of the most popular pet lizards in the world.
These arboreal geckos spend their nights climbing, hunting, and calling in humid forest canopy. Our reptile care guides include the full range of beginner-friendly species, and the crested gecko stands out for its simplicity.
Cresties are crepuscular and nocturnal. They sleep in foliage during the day and become active after lights out.
An enclosure packed with live or artificial plants gives them the security and climbing opportunities they need to stay calm and healthy.
Crested Gecko Enclosure: 18 × 18 × 24 In Vertical Build
Crested geckos live in the tree canopy. Height matters more than floor space.

The standard adult enclosure is an 18 × 18 × 24 in vertical terrarium, equivalent to an Exo Terra or ZooMed enclosure in that size class. Juveniles under 15g can start in a small deli cup or 6-gallon enclosure and be moved up as they grow.
Front-opening doors are standard for vertical enclosures and are far less stressful for the gecko than reaching in from above. Screen panels on the sides or back provide the cross-ventilation needed to prevent stagnant, overheated air.
- Substrate: Coconut fiber, organic topsoil, or ABG mix for bioactive setups. Depth of 2-3 inches supports live plant roots and beneficial microfauna.
- Plants: Pothos, bromeliads, and peperomia are safe, sturdy, and thrive under low light. Plants regulate humidity passively.
- Climbing: Cork bark rounds, bamboo tubes, and driftwood branches. Place at multiple heights.
- Food ledge: A magnetic feeding ledge or suction-cup dish placed mid-height is where most crested geckos prefer to eat.
Crested Gecko Temperature: 72-80°F With No Basking Lamp Required
This is the defining advantage of crested gecko keeping. Most homes stay within the 72-80°F range that crested geckos need without any supplemental heating.
No basking lamp, no thermostat, no heat mat. Room temperature is the target.
Heat is the greater danger. Sustained temperatures above 85°F cause heat stress and death within hours.
Crested geckos have no tolerance for high heat. In warm climates, a small fan or air conditioning is necessary in summer.
- Optimal range: 72-78°F during the day
- Nighttime: 65-72°F is fine and mimics natural temperature drop
- Danger zone: Above 85°F causes heat stress; above 88°F is potentially lethal
- UVB: A low-output 5.0 tube on a 10-12 hour cycle supports D3 synthesis and natural behavior patterns
Mist the enclosure once in the evening to raise humidity to 80-100%, then allow it to drop to 50-60% by morning. This wet-dry cycle mirrors the natural New Caledonian climate and prevents respiratory issues from sustained high humidity.
Crested Gecko Diet: Meal Replacement Powder Plus Insects
Crested geckos are unique among reptiles in that a commercial meal replacement powder (MRP) forms the core of their diet. Products like Repashy Crested Gecko Diet and Pangea Fruit Mix Complete provide a balanced, complete nutrition profile without live insects.
Many keepers successfully maintain crested geckos on MRP alone for years.
Live insects improve growth rates, breeding condition, and behavioral enrichment. Offer them as a supplement rather than the main diet.
Fruit is a natural part of the crested gecko diet in the wild. Small amounts of mashed ripe mango, fig, or papaya make a good occasional supplement, but commercial MRP already contains fruit components.
Additional fruit increases sugar load without adding missing nutrients.
Crested Gecko Health: Floppy Tail Syndrome and MBD Are Common
Crested geckos are hardy when kept correctly. The two most common preventable conditions are floppy tail syndrome and metabolic bone disease.
- Floppy tail syndrome: The tail drops to one side when the gecko sleeps clinging to glass. Caused by lack of horizontal resting spots. Add cork bark shelves and foliage at multiple heights so the gecko rests horizontally, not vertically.
- MBD: Soft jaw, inability to close the mouth fully, rubbery limbs. Caused by insufficient calcium or D3. Supplement MRP with calcium powder twice weekly and add a UVB lamp.
- Retained shed: Skin stuck around toes, tail tip, or eye area. Raise humidity and soak gently in shallow warm water. Dry environment is the cause.
- Cryptosporidiosis: Progressive weight loss, wasting. No cure. Source animals from reputable captive-bred breeders to minimize risk.
Note that crested geckos can drop their tails permanently. Unlike leopard geckos, crested gecko tails do not regenerate.
The tailless "frogbutt" appearance is common and does not affect health or quality of life.
Handling Crested Geckos: Fast Movers That Settle With Patience
Crested geckos are faster than leopard geckos and more likely to jump unexpectedly. Handle over a soft surface at first, close to the ground.
Let the gecko walk from hand to hand rather than gripping or restraining it.
Most crested geckos settle into calm handling after 2-4 weeks of short daily sessions. Some individuals remain flighty throughout their lives.
This is a personality variation, not a husbandry failure.
Crested Gecko Breeding: No Cooling Required, Pair at 35g Female Weight
Crested geckos breed without a formal cooling period, though a slight temperature drop in winter helps trigger breeding behavior. Females must reach 35-40g before pairing to ensure they can handle the nutritional demands of egg production.
Females lay 2 eggs per clutch every 30-45 days and can produce up to 8 clutches per year. Provide a deep moist laying box.
A depleted female loses weight rapidly and needs calcium supplementation increased to daily during breeding season.
