Introduction to Crested Geckos
Crested Geckos are nocturnal reptiles hailing from the lush rainforests of New Caledonia, an island group near Australia. First discovered in 1866, they were believed to be extinct until their rediscovery in 1994. These geckos are known for their expressive faces, licking their eyes to keep them clean, and their unique appearance – particularly the crests that run from their head to tail.
Scientific Classification
- Common Name: New Caledonian Crested Gecko
- Scientific Name: Rhacodactylus ciliatus (previously known as Correlophus ciliatus)
- Family: Eublepharidae
- Size: 8-10 inches when fully grown
- Lifespan: 15-20 years in captivity
Are Crested Geckos Good for Beginners?
Crested Geckos are an excellent option for beginners due to their relatively low maintenance requirements, friendly demeanor, and simple dietary needs. They can comfortably live in 20-gallon tanks filled with branches and leaves, making their enclosure setup uncomplicated. With proper care and handling, these exotic reptiles can make a delightful addition to any home.
Appearance
One of the most striking features of Crested Geckos is their “eyelashes,” which are actually small spines above their eyes that form part of their distinct crest. This crest runs from their eyes all the way to their tail, setting them apart from other reptiles. Crested Geckos lack eyelids, so these spiny projections help protect their sensitive eyes from debris and damage as they navigate through their natural habitat. To maintain their eye health, they regularly lick their eyes to keep them clean.
Crested Gecko Size
Adult Crested Geckos typically measure between 8 to 10 inches in length and weigh between 30 to 35 grams. They reach their full size within the first 12 months of life. Males and females are similar in size, weight, and appearance. However, males can be distinguished by the presence of hemipenes – paired reproductive organs visible externally as bulges on either side of their tails. Hatchlings are born at a size of approximately ⅖ to 1 inch.
Colors and Patterns
Crested Geckos exhibit a wide range of colors and patterns, further adding to their appeal. Their back often features large dark lateral stripes and can be found in shades of light tan, peach, and reddish-brown. There are three primary color morphs found in Crested Geckos:
- Tiger morphs: Display patterned bellies along with dark stripes on lighter skin.
- Patternless morphs: Lack patterns and have a solid color throughout their body.
- White-fringed morphs: Exhibit white or yellow coloration on their crests.
These geckos also possess the ability to change their color slightly for camouflage or communication purposes.

Crested Gecko Diet
A well-balanced diet is crucial for your Crested Gecko’s health and well-being. Feeding a combination of insects and fruits helps prevent nutrient imbalances and calcium deficiencies, which could lead to health issues such as metabolic bone disease. Crested Geckos are omnivores, consuming a variety of fruits and insects as part of their diet.
What Do Crested Geckos Eat?
In the wild, Crested Geckos primarily feed on small insects and overripe fruits. Their preferred insects include small roaches and crickets, which should be dusted with calcium and vitamin D3 before being offered a couple of times per week. For their fruit intake, consider providing small pieces of banana, peach, passion fruit, or apricot. Mashed fruit can also be an option.
Juveniles and hatchlings require the same diet, but in smaller quantities. Note that hatchlings will not eat for the first few days of their lives, as they rely on stored yolk for sustenance. Crested Geckos prefer ripe or overripe fruits, so be sure to remove any uneaten food after a week to maintain cleanliness in their enclosure.
Feeding should ideally take place in the late evening, as Crested Geckos are nocturnal creatures. Provide clean water at all times, using a shallow bowl to prevent drowning.
Crested Gecko Lifespan and Health
With proper care, a balanced diet, and regular husbandry, Crested Geckos can live up to 20 years or more in captivity. Their health is mainly influenced by their environment and diet. Overfeeding can lead to obesity, while a lack of calcium may result in metabolic bone disease.
Crested Geckos have endolymphatic sacs on the roofs of their mouths to store calcium. Insufficient calcium or poor breeding practices can lead to abnormally shaped eggs (post-ovulatory dystocia) since a large calcium reserve is required for proper egg formation.
Keep an eye on your gecko’s feces, which should be part brown (from food waste) and either solidified or liquid urine. Slightly runny feces are acceptable, but if they remain runny or bloody for multiple days, consult a veterinarian.
Ensure that your Crested Gecko is well-hydrated and healthy to facilitate problem-free shedding of their skin. Maintain humidity levels between 60-70% in their tank, misting daily with a spray bottle.
Signs of a Healthy Crested Gecko
- Hiding and sleeping during daylight hours.
- Regularly licking their eyeballs.
- Emerging at night to feed.
Symptoms of Sickness
- Sudden weight loss.
- Darker skin color than usual.
- Abnormal or bloody feces.
Crested Gecko Habitat
Crested Geckos are native to the tropical rainforests of New Caledonia, specifically the Isle of Pines and Grand Terre. These islands boast warm, humid environments with thick vegetation, which the geckos utilize for cover during the day and for hunting at night.
Crested Gecko Tank
Glass tanks are ideal for Crested Geckos, as they enjoy climbing smooth surfaces. A 20-gallon tank with a height of 4-6 feet provides ample space for your gecko to explore:
- Tank Type: Glass tank.
- Tank Size: 20-gallon capacity.
- Lighting: None required.
- Substrate: Soil or paper towels.
Hatchlings and juveniles can be housed in smaller 10-gallon tanks but should be transferred to larger enclosures by the time they reach one year of age.
To ensure your Crested Gecko feels secure in its environment, provide plenty of hiding spots such as vegetation, plants, branches, logs, leaves, and egg cartons.
Tank Setup
No additional lighting or cage hood is required for Crested Geckos, as they are nocturnal creatures. Avoid disrupting their circadian rhythms by turning off any nearby lights when the sun goes down, mimicking natural sunlight patterns.
While it is not necessary, you can use a UV light during the day if their tank is not situated near natural lighting.
Maintain a tank temperature of around 75°F, as Crested Geckos do not require much heat beyond room temperature. Keep humidity levels between 60-70%, misting daily with a spray bottle and wiping down the glass walls after five minutes.
Use a humidity gauge to ensure the correct environment for your gecko.
Substrate
Crested Geckos are not particular about their substrate. You can choose between soil or paper towels, depending on your preference. Soil closely mimics their natural environment and supports live plants, while cypress mulch or coconut fibers make excellent alternatives. Paper towels are more disposable and can be cleaned quickly during spot cleaning.
Ensure the substrate does not increase humidity excessively and is easy to clean.
Tank Cleaning
Remove excess food weekly and spot clean the tank as necessary. Perform a deep clean every month, which includes a full substrate change. Regular cleaning helps maintain your reptile’s health.
If bacterial growth occurs, remove your gecko from the tank, change the substrate, and deep clean the enclosure.
Typical Behavior
Crested Geckos tend to hide in lower brush during the day to avoid sunlight and predators. They become more active at night, climbing through tree canopies to hunt insects and scavenge for fruit. As arboreal reptiles, they are well-adapted to life in trees.
When threatened, Crested Geckos may stand on their hind legs and hiss. In extreme cases, they may lose their tail as a defense mechanism. They communicate with tank mates through high-pitched chirping sounds, which they also emit when sensing nearby predators.
In captivity, Crested Geckos will display natural behaviors such as hiding during the day and hunting for food at night.
Males can be aggressive towards one another, particularly when there are few females present. Females may show aggression if they are not receptive to mating with an advancing male.
Do Crested Geckos Enjoy Being Handled?
Crested Geckos are generally docile and tolerate being handled well. They are not known for being aggressive towards their handlers and rarely bite. With proper care and handling, these lizards can make a wonderful addition to any household.
Baby Crested Geckos
Baby Crested Geckos are independent from the moment they hatch, with neither parent participating in raising them. After hatching, they will not eat for the first few days, relying on stored yolk for nourishment. Once they shed their skin for the first time, they can consume an adult diet in smaller portions, regulating their food intake as needed.
How Much Does a Crested Gecko Cost?
Crested Geckos are widely available from responsible breeders, with prices typically ranging from 150. Exporting Crested Geckos from New Caledonia has been illegal since their rediscovery in 1994. During mating, males exhibit jerky movements as they approach females. If the female is receptive, the male will climb on her back and gently bite her neck. After copulation, the female may lay two eggs 30-40 days later. Female geckos can retain sperm, allowing for fertilization without additional mating.
Eggs hatch 60-70 days after being laid, with the tank temperature affecting the sex of the hatchlings. Warmer temperatures result in a higher probability of male offspring, while cooler temperatures yield more females. Higher incubation temperatures also lead to faster egg development.
