Overview
What is this animal?
- Native to New Caledonia, the crested gecko is an arboreal, nocturnal species named for the fringe of scales above its eyes.
- Long thought extinct, it is now a widely kept pet gecko thanks to its straightforward care, gentle nature and the availability of complete powdered diets.
- Crested geckos have adhesive toe pads and a prehensile tail, though adults frequently drop the tail and do not regrow it.
- They tolerate ordinary room temperatures better than most reptiles, which keeps running costs low, but they need height, humidity and climbing cover to feel secure.
Temperament
- Crested geckos are docile but can be skittish and are capable jumpers, so handle low over a soft surface until they settle.
- They are nocturnal and most active in the evening.
- With gentle, regular handling many become calm and will hop onto a hand.
- They are best housed singly.
- Males are territorial and will fight, and females can also compete or show aggression over food and space.
- Solo housing removes the risk of stress and injury and is the responsible default for this species.
A good fit for
- Beginners wanting low running costs
- Keepers without space for heat lamps
- People wanting an easy complete diet
- Evening-active pet keepers
Common mistakes to avoid
- Overheating above 28-29C
- Cohabiting geckos, causing fights
- Humidity staying too high (mould)
- Feeding only fruit or baby food
Enclosure
Minimum 2,030 cm² of floor (315 sq in) · 45 × 45 × 60 cm
Must be housed alone. Solitary; house singly
- Use a tall, well-ventilated vivarium of at least 45x45x60cm for one adult, densely furnished with branches, cork bark and foliage for climbing and hiding.
- As an arboreal species, vertical space matters more than floor area.
- A bioactive setup with live plants helps hold humidity.
- Keep temperatures around 22-26C; sustained temperatures above 28-29C are stressful, so a strong basking lamp is usually unnecessary in a typical home.
- A low-output UVB tube is beneficial.
- Maintain humidity around 60-80% by misting once or twice daily, allowing the enclosure to dry between mistings to prevent mould and respiratory problems.

Diet
- Crested geckos do well on a commercial complete crested gecko diet (CGD), a powdered fruit-and-insect mix made up with water and offered in a shallow dish several times a week.
- This food can meet their full nutritional needs, which makes feeding simple.
- Supplement with gut-loaded, calcium-dusted live insects such as crickets or dubia roaches once or twice weekly for enrichment and protein.
- Avoid feeding only baby food or fruit, which is unbalanced and causes deficiencies.
- Provide fresh water daily, though they often drink droplets from misted surfaces.
Health
- Look for clear eyes, intact toe pads, smooth shedding and steady weight.
- Common problems include metabolic bone disease linked to poor calcium or UVB, retained shed on the toes that can cut off circulation, and floppy tail syndrome.
- Overheating is a frequent and serious husbandry error that can be rapidly fatal.
- A dropped tail is normal for adults and not an emergency, but a sudden change in appetite, weight or activity warrants attention.
- As with all reptiles, seek a vet experienced with exotics.
- Good ventilation and correct humidity prevent most respiratory and skin issues.
Is your enclosure big enough?

Is this urgent?
Small geckos dehydrate and lose condition quickly, and the tail is the fuel gauge.

Tremors, weak grip, or a jaw that will not close properlyGo now. Calcium and D3 deficiency.
NowToday
Tail visibly thinning in a species that stores fat thereWeigh, then call with the trend. The fat store goes before the body condition does.
TodayStuck shed around the toes or over the eyesRaise humidity, offer a damp hide, and call if it is not clear within a day. Constricting shed rings cost toes. This is the most common avoidable injury in geckos.
TodayRefusing food with weight lossCheck the cool-end and warm-end temperatures, then call. A gecko that cannot reach its preferred temperature cannot digest.
TodayThis is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a crested gecko eat that?
Geckos split into two diets that share almost nothing: insectivores like the leopard gecko, and the fruit-and-insect species like the crested gecko. Check which one you have.

What it really costs
Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.
Bedding and substrate
Match the substrate to the species' humidity, and never let a small gecko stand on anything it can swallow whole.
Safe
Topsoil and play sand mix for arid geckosPacks firm, holds a burrow, and is what a leopard gecko would actually stand on.
safeCoco fibre and orchid bark for tropical geckosHolds the humidity a crested or day gecko needs.
safePaper towelCorrect for quarantine, for hatchlings, and for any animal whose output you are watching.
safeWith a caveat
Sphagnum mossExcellent in a humid hide, poor as a whole-floor substrate — it stays wet.
with a caveatNever
Calcium sandSold as digestible, which is exactly why it gets eaten. Implicated in impaction.
neverCrushed walnut shellSharp and indigestible.
neverLoose play sand alone for hatchlingsToo easy to swallow at that size.
neverA humid hide is not optional for most geckos, whatever the main substrate is. Most stuck-shed problems trace back to its absence.
