Crested Gecko Care Guide for Beginners

Introduction

Crested geckos (Correlophus ciliatus) are one of the best pet reptiles for beginners. Once thought to be extinct, they were rediscovered in New Caledonia in 1994 and have since become hugely popular in the pet trade thanks to their gentle temperament, low-maintenance care requirements, and incredible variety of colors and patterns.

This guide covers everything you need to know to set up a proper crested gecko habitat and provide excellent care from day one.

Natural Habitat & Behavior

Crested geckos are native to the tropical forests of southern New Caledonia, a group of islands in the South Pacific. Understanding their natural environment is key to proper husbandry:

• •They are arboreal. Crested geckos live in trees and bushes. They need vertical space — this is the opposite of leopard geckos, which are ground-dwelling.
• •They are nocturnal. Most active at night, they spend daytime hours hiding in foliage.
• •They have adhesive toe pads. Crested geckos can climb smooth glass, branches, and even ceilings. Your enclosure needs a secure top.
• •They cannot regenerate their tails. If a crested gecko drops its tail (from stress or being grabbed), it will not grow back. "Tailless" or "frogbutt" cresties are common and live perfectly healthy lives, but it's best to avoid tail loss through careful handling.

Enclosure Setup

Size

• •Juveniles (under 15 grams): A smaller enclosure is actually better — 7-10 gallon or a 12" x 12" x 18" terrarium. Babies can have difficulty finding food in a large space.
• •Adults: Minimum 18" x 18" x 24" (roughly 20 gallons, oriented vertically). Many keepers prefer 24" x 18" x 24" or larger for a single adult.
• •Orientation matters: Taller is better. A standard fish tank turned on its side is not appropriate. Front-opening terrariums designed for arboreal species are ideal.

Substrate

• •Paper towel: Best for juveniles and quarantine. Easy to monitor droppings and maintain hygiene.
• •Coconut fiber (Eco Earth) or ABG mix: Good for adults. Holds humidity well and allows for live plants. A bioactive setup with springtails and isopods is excellent for long-term maintenance.
• •Sphagnum moss: Can be used as a top layer or in humid hide areas to boost moisture retention.

Avoid: Loose substrates with large particles for juveniles, and any substrate that could mold without a cleanup crew.

Temperature

Crested geckos thrive in cooler temperatures compared to many reptiles — this is one reason they're easy to keep:

• •Ideal range: 72-78°F (22-25°C)
• •Absolute maximum: 82°F (28°C). Temperatures above this can cause heat stress and even death. Crested geckos are sensitive to overheating.
• •Nighttime drop: A gentle drop to 65-72°F (18-22°C) at night is natural and beneficial.

In most homes, room temperature is sufficient. If your home stays in the 72-78°F range, you may not need supplemental heating at all. If you do need heat, a low-wattage ceramic heat emitter or small deep heat projector on a thermostat is the safest option.

Never use: Heat mats on the side of the enclosure (they can overheat the small airspace), or high-wattage basking bulbs.

Humidity

This is one of the most important aspects of crested gecko care:

• •Daytime humidity: 50-60%
• •Nighttime humidity (after misting): 70-80%
• •Misting schedule: Mist the enclosure thoroughly in the evening. Many keepers also do a lighter morning mist. The enclosure should dry out somewhat between mistings — constant dampness promotes mold and respiratory issues.

A digital hygrometer is essential for monitoring. Analog "dial" hygrometers are notoriously inaccurate.

Crested geckos often drink water droplets from leaves and enclosure walls after misting. A small water dish should also be provided, placed where the gecko can easily access it.

Lighting

• •UVB is not strictly required but is increasingly recommended. A low-output UVB bulb (5% T8 or equivalent shade-dweller bulb) can support vitamin D3 synthesis and encourage more natural behavior.
• •Provide a natural day/night cycle. Ambient room light or a low-wattage LED on a timer (12 hours on, 12 hours off) is sufficient.
• •Do not use bright, high-output lighting. Crested geckos are nocturnal and will be stressed by intense light.

Decor & Enrichment

Crested geckos need plenty of climbing surfaces and hiding spots:

• •Live or artificial plants — Pothos, bromeliads, and ficus are popular live options. Artificial plants work fine too. Dense foliage makes your gecko feel secure.
• •Branches and vines — Cork bark, bamboo, and grapevine provide climbing paths. Horizontal and angled branches are used most.
• •Hides — Cork bark tubes, coconut halves, and magnetic ledges provide resting spots at various heights. Offer hides at both the top and bottom of the enclosure.

A well-decorated enclosure is not just aesthetic — it directly impacts your gecko's stress levels and health.

Diet & Nutrition

One of the biggest advantages of crested geckos is their diet. Unlike leopard geckos, which require live insects, crested geckos eat a commercial powdered diet as their primary food source.

Complete crested gecko diets (CGD)

These are powdered meal replacement formulas that you mix with water:

• •Pangea — The most popular brand. Flavors include Fruit Mix with Insects, Watermelon, and Breeding Formula. All are nutritionally complete.
• •Repashy — Another excellent option. "Grubs 'N' Fruit" and "Classic" are popular formulas.

These diets are formulated to meet all of a crested gecko's nutritional needs. They are the staple diet — not a supplement.

How to feed CGD

• •Mix the powder with water to a ketchup-like consistency.
• •Offer in a small, shallow dish (magnetic ledge-mounted dishes work well for arboreal setups).
• •Replace every 24-48 hours. Fresh food is important, especially in warm enclosures where the mix can spoil.
• •Offer food in the evening when your gecko becomes active.

Insects as supplementation

While CGD is nutritionally complete, offering live insects 1-2 times per week provides enrichment and extra protein:

• •Dubia roaches — Best overall feeder
• •Black soldier fly larvae — High in calcium
• •Crickets — Widely available, but remove uneaten crickets
• •Size rule: Insects should be no wider than the space between the gecko's eyes.

Dust insects lightly with calcium powder when offering.

What NOT to feed

• •Baby food (not nutritionally complete)
• •Fruit alone (not balanced)
• •Wild-caught insects (pesticide/parasite risk)
• •Mealworms (too tough for most crested geckos to digest properly)

Humidity & Shedding

Crested geckos shed their skin regularly as they grow. Proper humidity is the single most important factor for clean sheds.

• •Increase misting slightly if you notice your gecko is about to shed (skin may appear dull or whitish).
• •Most crested geckos shed at night and eat their shed skin — you may never see it happen.
• •Stuck shed is usually a sign of low humidity. Check the toes and tail tip especially. Gently soak the affected area with a warm damp cloth if needed. Do not pull shed.

Handling

Crested geckos are generally docile but can be jumpy, especially as juveniles.

Taming tips

• •Wait at least a week after bringing your gecko home before handling.
• •Start with 5-minute sessions and work up to 15-20 minutes.
• •Handle in the evening when they're naturally awake.
• •Let the gecko walk from hand to hand — "hand walking" is the best technique. They'll jump between your hands.
• •Move slowly and stay close to a soft surface.
• •Never grab the tail. The tail will not grow back if dropped.
• •Young crested geckos (under 10 grams) are very fast and fragile. Handle with extra care, or wait until they're a bit bigger.

Behavior to expect

• •Barking/chirping: Crested geckos can vocalize! Small chirps and barks are normal, especially when startled.
• •Fired up/fired down: Crested geckos change color based on mood, activity, and time of day. "Fired up" (darker, more vivid) usually occurs at night. "Fired down" (lighter, paler) is common during the day while resting. Both states are completely normal.
• •Wall surfing: Pacing along the glass can indicate stress, hunger, or just exploration. If persistent, check husbandry parameters.

Health & Common Issues

Signs of a healthy crested gecko

• •Active and alert during evening hours
• •Clear eyes, straight spine
• •Healthy weight (not bony or obese)
• •Clean vent area
• •Regular eating and defecation
• •Smooth, complete sheds

Common health concerns

Metabolic bone disease (MBD): Caused by calcium deficiency. Symptoms include wavy tail, kinked spine, tremors, and difficulty climbing. Use a quality CGD (they include calcium) and consider low-level UVB. MBD is preventable with proper nutrition.

Mouth rot (stomatitis): Bacterial infection presenting as redness, swelling, or cheesy buildup around the mouth. Requires veterinary treatment with antibiotics.

Respiratory infections: Usually caused by constantly high humidity without ventilation, or temperatures that are too low. Symptoms: labored breathing, mucus. Ensure your enclosure has adequate ventilation and dries out between mistings.

Parasites: Intestinal parasites are common in captive reptiles. A fecal test from a reptile vet is a good idea for any new gecko.

Floppy tail syndrome (FTS): The tail bends or hangs at an unnatural angle, sometimes seen in geckos that rest upside down on smooth surfaces. While cosmetic rather than dangerous, providing rough-textured perches and horizontal resting spots can help prevent it.

Veterinary care

Find a reptile-experienced vet before you need one. The Association of Reptilian and Amphibian Veterinarians (ARAV) maintains a directory searchable by location.

Choosing a Crested Gecko

When selecting your first crested gecko, here's what to look for:

• •Active behavior when gently disturbed (especially in the evening)
• •Clear, alert eyes — no retained shed around the eyes
• •Straight spine with no visible kinks
• •A healthy weight (not bony hips or spine)
• •Clean vent area (no caked feces or swelling)
• •Ask the breeder about the gecko's feeding response and hatch date

Buying from a reputable breeder gives you the best chance of getting a healthy, well-started animal with known genetics.
