Crested Gecko: Care Guide, Diet, Setup & Lifespan

QUICK ANSWER
Crested geckos are the most low-maintenance lizard available: no live insects required, no basking lamp, and a room-temperature enclosure that costs almost nothing to heat. Expect a 15-20 year lifespan, a 18 × 18 × 24 in vertical enclosure, and a diet centered on commercial meal replacement powder.

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
WARNING
Never place a crested gecko enclosure near a south-facing window or in a room without climate control in summer. A single afternoon of direct sun can raise enclosure temperature above 90°F and kill the gecko before you notice.

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.

Mix MRP with water to a smooth applesauce consistency. Place in a magnetic feeding ledge or small ramekin. Replace every 24-48 hours before it molds. Feed every other day for juveniles, 3x per week for adults. Both Repashy and Pangea are complete diets when fed as directed.
Offer small crickets, dubia roaches, or black soldier fly larvae once or twice a week. Dust with calcium (no D3) before offering. Insects should be no larger than the space between the gecko's eyes. Remove uneaten insects within 1 hour to prevent stress biting.

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.

CARE TIP
Offer the MRP at dusk when the gecko becomes active. Crested geckos fed during their active period consume significantly more than geckos offered food during daytime when they are sleeping and stress-averse to disturbance.

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.

✓ PROS
No basking lamp or heat mat needed in most homes
Commercial MRP reduces live insect dependency
15-20 year lifespan
Extremely diverse morph selection
Handles well once established
✗ CONS
Cannot tolerate heat above 85°F
Tail loss is permanent (no regeneration)
Crepuscular: active mostly at night
Needs high humidity (60-80%)

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.

Egg Incubation for Crested Geckos
Crested gecko eggs can be incubated at room temperature (68-74°F) in moist vermiculite. Eggs hatch in 60-120 days depending on temperature. Cooler incubation = longer incubation time but often more robust hatchlings. Do not use high-heat incubators. Mark the top of each egg at collection to prevent rotation during incubation.
Live insects are beneficial but not required. A quality MRP like Repashy or Pangea provides complete nutrition as the sole diet for most crested geckos throughout their lives.
Tail autotomy is a natural stress response. Common causes: rough handling, a too-aggressive enclosure mate, or a feeder insect biting the tail. Crested gecko tails do not regenerate.
Anything above 85°F causes heat stress. Above 88°F for extended periods is potentially fatal. Keep the room air-conditioned in summer.
Once per day in the evening, raising humidity to 80-100%, then allowing it to drop to 50-60% before the next misting. Do not keep the enclosure wet all the time.
Two females can cohabit in a large vertical enclosure. Never house two males together. Remove the male after breeding to prevent the female from being stressed by constant mating attempts.
THE BOTTOM LINE
Crested geckos are the easiest lizard to maintain correctly. No basking lamp, no thermostat, and a diet that comes in a powder you mix with water. If you can keep your house between 72-80°F and mist an enclosure once a day, you have everything this species needs. Other New Caledonian options worth knowing about include the gargoyle gecko and the more challenging tokay gecko. For a complete leopard gecko tank setup comparison, that guide covers how ground-dwelling gecko housing differs from vertical builds like this one. Our gecko substrate guide covers coconut fiber and ABG options that apply equally here. For keepers also housing insectivorous lizards, gut-loading feeders with strawberries, bananas, grapes, leafy greens, and carrots boosts nutritional value before every feeding. The leopard gecko is the natural comparison point for keepers deciding between gecko species.
