Crested geckos (Correlophus ciliatus) are one of the best reptile pets available today — hardy, handleable, and genuinely fascinating to watch. Once thought extinct, they were rediscovered in 1994 and have since become a staple in the reptile hobby worldwide.

Quick Answer: Crested geckos are arboreal lizards native to New Caledonia that thrive at 68–80°F, 60–80% humidity, and need a tall, vertical enclosure of at least 18×18×36 inches. They eat a combination of commercial meal replacement powder (MRP) and live insects, and can live 15–20 years in captivity with proper care.

What Is a Crested Gecko?

Crested geckos are small, nocturnal lizards named for the hair-like crests running from their eyes down their backs. They belong to the family Diplodactylidae and are endemic to the islands of New Caledonia in the South Pacific [1].

Adults typically reach 6–8 inches in total length, with roughly half of that being tail. They weigh between 35–65 grams when fully grown.

Unique Physical Traits

Crested geckos have several standout features that make them easy to identify:

• Prehensile tail (when present) for gripping branches
• Lamellae (sticky toe pads) that allow them to climb smooth surfaces
• No eyelids — they lick their eyes to keep them clean
• Fringed crests running from head to base of tail
• Color-changing ability called "firing up" — they shift between lighter ("fired down") and darker, more vibrant hues ("fired up")

Common Myth: "Crested geckos can regrow their tails like other geckos." Reality: Unlike leopard geckos, crested geckos that drop their tails do NOT regenerate them. Tail loss is permanent, though the gecko remains healthy without it.

Taxonomy at a Glance

According to the IUCN Red List, wild crested gecko populations face pressure from habitat loss and introduced predators like rats and fire ants. Captive breeding has helped reduce collection pressure on wild populations significantly.

Crested Gecko Behavior and Temperament

Crested geckos are among the most docile reptiles available to beginner keepers, but they're also highly active and entertaining at dusk and dawn.

During the day, they tend to hide and sleep in foliage or cork bark. As temperatures drop in the evening, they become alert, vocal (a soft chirping sound), and begin hunting.

What Do Crested Geckos Do All Day?

Most of the time, crested geckos are sleeping. They're crepuscular to nocturnal animals, meaning peak activity happens around sunrise and sunset.

A typical 24-hour cycle looks like this:

1. Daytime (6am–6pm) — Hidden in foliage, motionless, sleeping
2. Dusk (6pm–8pm) — Waking up, exploring, hunting insects
3. Night (8pm–midnight) — Peak activity, eating, climbing
4. Pre-dawn (4am–6am) — Second activity spike before settling down

Pro Tip: Schedule feeding time for the evening when the gecko naturally wakes up. This reduces stress and improves feeding response.

Handling Temperament

Crested geckos tolerate handling well compared to most lizards. Most individuals become calm and curious with regular, short sessions.

Start with 5-minute sessions every other day. Build up to 10–15 minutes once the gecko is comfortable. Always let the gecko walk between hands rather than gripping it — this reduces stress and mimics natural movement.

Setting Up the Perfect Crested Gecko Enclosure

Crested geckos need a tall, vertical enclosure with plenty of climbing structure, plants, and hiding spots. A horizontal fish tank simply doesn't work — these are arboreal animals that spend their lives in trees.

Enclosure Size Requirements

• Hatchlings (0–3 months): 6-quart deli container or 12×12×18" enclosure
• Juveniles (3–12 months): 12×12×18" minimum
• Adults: 18×18×36" minimum — bigger is always better

Glass terrariums with front-opening doors and mesh tops are the keeper community's go-to choice. They allow proper airflow while retaining humidity.

Decor and Enrichment

Think vertical when setting up the enclosure:

• Cork bark tubes and flats for hiding
• Sturdy horizontal branches at multiple heights for perching
• Live or artificial pothos, philodendron, or bromeliads for cover
• Magnetic feeding ledges at mid to upper height
• Coconut fiber or bioactive substrate (coco coir + peat + orchid bark) on the floor

Pro Tip: Bioactive setups with live plants, springtails, and isopods dramatically reduce cleaning frequency and create a more natural environment. Check out our Best Crested Gecko Humidity: Your Complete Guide (2026) for substrate recommendations that support both plants and geckos.

Temperature and Humidity: The Two Numbers That Matter Most

Crested geckos come from a cool, humid subtropical climate — they need temperatures between 68–78°F and humidity between 60–80% [2].

Most keepers in temperate climates can maintain this range with room temperature alone during spring and fall. No heat lamp is required in most homes.

Temperature Guidelines

For homes that run hot in summer, a small USB fan directed at the enclosure mesh can bring temperatures down 3–5°F. See our Best Crested Gecko Heating and Temperature Setup (2026) for full options.

Humidity Management

Crested geckos hydrate largely through dew and misting rather than standing water.

• Mist one or both sides of the enclosure once or twice daily
• Allow humidity to drop to 40–50% between misting cycles
• This wet-dry cycle prevents respiratory infections and mold
• A digital hygrometer is non-negotiable — guessing humidity doesn't work

For consistency, a Best Crested Gecko Misting System: A Drip-by-Drip Guide can automate the process entirely.

Common Myth: "Crested geckos need a water bowl." Reality: Most crested geckos rarely drink from standing water. They lap droplets from leaves and glass after misting. A shallow water dish won't hurt, but misting is the primary hydration method.

Diet and Nutrition: What Crested Geckos Actually Eat

Crested geckos are omnivores that thrive on a combination of commercial meal replacement powder (MRP) and live feeder insects. MRP alone can sustain them, but insects add protein, enrichment, and behavioral stimulation [3].

Commercial MRP Options

The keeper community has largely standardized on a few trusted brands:

• Pangea Fruit Mix — highly palatable, good for picky geckos
• Repashy Crested Gecko Diet — original formula, widely respected
• Black Panther Zoological (BPZ) — popular in Europe and among breeders

Mix MRP to a ketchup-like consistency with water. Offer every other day and remove uneaten food within 24 hours to prevent mold and fruit flies.

Live Feeder Insects

Offer live insects 1–2 times per week for juveniles and once a week for adults. Top feeder options include:

• Dubia roaches — high protein, low fat, easy to digest
• Black soldier fly larvae (BSFL) — excellent calcium-to-phosphorus ratio
• Crickets — stimulating but require gutloading
• Small mealworms (limited) — high fat, feed sparingly

Calcium and Supplementation

Calcium deficiency is one of the most common health problems in captive crested geckos. According to Reptifiles, a high-quality MRP diet typically provides adequate calcium, but keepers who feed primarily insects must dust feeders with calcium powder.

• Dust insects with calcium without D3 twice a week
• Use calcium with D3 once a week if no UVB lighting is provided
• Consider a multivitamin supplement once every 2 weeks

Pro Tip: Low calcium combined with high phosphorus causes Metabolic Bone Disease (MBD). If the gecko's jaw looks soft or limbs seem rubbery, consult a reptile vet immediately. See our Best Crested Gecko Calcium: A Complete Nutrition Guide for product picks.

Lighting for Crested Geckos

Crested geckos are nocturnal and don't require intense UVB lighting, but low-level UVB exposure (2.0–5.0 UVI) appears to improve long-term health and D3 synthesis.

The consensus among reptile vets as of 2026 is shifting toward providing some UVB for all reptiles, even nocturnal species. Research from VCA Animal Hospitals supports that ambient UVB reduces reliance on dietary D3 supplementation.

Lighting Schedule

• Photoperiod: 12 hours on / 12 hours off year-round, or follow natural seasonal variation
• UVB bulb: T5 HO 5.0 or 6% UVB, positioned 12–18 inches above the gecko's basking zone
• Replace UVB bulbs every 12 months even if still producing visible light
• Always provide shaded areas so the gecko can self-regulate exposure

Common Beginner Mistakes to Avoid

New crested gecko keepers consistently make the same preventable errors. Knowing these in advance saves money, stress, and potentially the gecko's life.

Mistake 1: Keeping the Enclosure Too Hot

Temperatures above 85°F can kill a crested gecko within hours. Many beginners add a basking lamp out of habit from keeping bearded dragons or other desert reptiles — this is dangerous for Correlophus ciliatus.

No heat lamp is needed in most homes. Check ambient room temperature first before adding any heating device.

Mistake 2: Handling Too Soon or Too Long

Bringing a new gecko home and immediately handling it causes severe stress. Allow 2 full weeks of no-touch adjustment time before the first handling session.

After that, keep sessions under 10 minutes for the first month. Watch for stress signals: dark coloration, fast breathing, and attempting to jump or flee.

Mistake 3: Not Monitoring Humidity Correctly

Humidity swings — either constantly soaked or chronically dry — both cause problems. The goal is a wet-dry cycle: high humidity right after misting, dropping to 40–50% before the next misting.

Purchase a digital hygrometer (not the dial type — they're notoriously inaccurate) before bringing the gecko home.

Mistake 4: Feeding Only Insects or Only MRP

Some beginners feed only crickets because the gecko seems enthusiastic about live prey. A diet of crickets alone leads to nutritional deficiencies quickly.

Always keep MRP as the dietary foundation. Insects are a supplement, not the staple.

Crested Gecko Health: Signs of a Healthy Gecko

A healthy crested gecko is alert at dusk, maintains body weight, has clear eyes, and shows consistent feeding behavior. Any deviation from these signs warrants closer monitoring.

Health Checklist

Positive signs:

• Eyes clear and reactive
• Body feels firm, not sunken at the flanks
• Active during evening hours
• Eating MRP and insects regularly
• Smooth, complete sheds

Warning signs (consult a vet):

• Sunken eyes or flanks (dehydration)
• Soft jaw or kinked spine (MBD)
• Labored breathing or wheezing (respiratory infection)
• Persistent lethargy outside of normal brumation
• Red or swollen tissue near vent (infection)

Pro Tip: Weigh the gecko weekly using a small kitchen scale. A steady weight in a juvenile means healthy growth. Sudden weight loss in any gecko warrants a vet visit. Document the numbers — vets will ask.
