Crested Gecko Care Guide: Habitat, Diet, Size & Lifespan

Is This Species Right for You?

The crested gecko is frequently sold as an easy first reptile, and the quick-facts label of beginner-friendly is fair as far as survival goes — this species tolerates room-temperature housing without supplemental heat in most homes and does not strictly require UVB. But easy to keep alive is not the same as easy to keep well, and the difficulty rating here is intermediate for a reason: getting the humidity cycle, feeding routine and enclosure size right takes more ongoing attention than the marketing suggests.

Space is the first honest cost. A single adult needs a minimum 18 x 18 x 24 in (45 x 45 x 60 cm) front-opening enclosure — a floor-to-ceiling commitment in a bedroom, not a shoebox on a shelf. Ongoing cost is modest, $15–$35 a month for diet powder, feeder insects and supplies, but the first setup runs $250–$500 once a correctly sized enclosure, lighting and live planting are accounted for.

This is also a 15–20 year commitment when housed and fed correctly, worth planning for before purchase, whether through browsing available animals or reading further in the wider care guide library.

Handling tolerance is moderate, not high: most individuals settle, but they are fast, jumpy, and drop their tails under stress — a tail that does not regrow. That makes this a poor first reptile for a young child to handle unsupervised, though it is a fine household pet once an adult manages handling sessions and sets the rules for children.

Natural History and Wild Behaviour

Correlophus ciliatus is native to New Caledonia, a South Pacific island group, where it occupies humid forest habitat on Grande Terre and the Isle of Pines. It was believed extinct until its rediscovery in 1994, and wild population data remain poorly quantified even now — a rare case where a staple of the reptile hobby is still barely studied in its native range.

In the wild this is a crepuscular-to-nocturnal species, most active at dusk, dawn and after dark, and it is arboreal by habit — it spends the majority of its time climbing through forest canopy and understory foliage rather than moving across the ground. That single behavioural fact should shape every enclosure decision that follows: this is a species furnished for height and horizontal branch coverage, not floor space. Diet in the wild leans omnivorous and frugivorous, taking fruit, nectar and small invertebrates opportunistically rather than hunting as a dedicated predator, which is why a manufactured, nutritionally complete diet works so well as a captive staple.

Conservation status is not reassuring: the species is assessed as Vulnerable on the IUCN Red List, and wild collection from New Caledonia has been banned by the New Caledonian government since the mid-2000s, so any wild-caught animal in trade today would be there illegally. It is listed on CITES Appendix II following the CoP19 listing of New Caledonian geckos, which affects international shipment paperwork rather than domestic keeping or sale. Every crested gecko sold through reputable channels, including sellers on ReptileAds, is captive-bred — the species is now one of the most commonly bred reptiles in the hobby.

Enclosure Size and Setup

Enclosure dimensions in this guide are minimums, not targets — bigger is genuinely better for an animal that spends its life climbing, and a keeper with the space should exceed every figure below. A hatchling or juvenile needs a minimum 12 x 12 x 18 in (30 x 30 x 45 cm) enclosure with dense fine-mesh cover and several climbing and hiding points to keep a small animal from feeling exposed. As growth approaches subadult size, upgrade to the adult minimum: 18 x 18 x 24 in (45 x 45 x 60 cm), roughly 33–40 gallons (125–150 L) equivalent, oriented taller than wide. A recommended setup gives meaningfully more height and horizontal branch runs than the minimum footprint; an excellent setup is a large, densely planted vertical enclosure with multiple basking and retreat zones so an animal is never forced to choose between thermoregulating and hiding.

Front-opening glass or PVC enclosures are strongly preferred over top-opening tanks for an arboreal, jumpy species — reaching in from above startles the animal and increases fall and tail-drop risk. Ventilation needs to be adequate without collapsing humidity retention entirely; mesh panels or vents sized for cross-flow, rather than a fully mesh top, work better for maintaining the nightly humidity spike.

Provide at least two full hides — one on the warm side, one on the cool side — plus a dedicated humid hide, and enough horizontal and diagonal climbing surfaces (cork rounds, branches) that the animal is never left standing on the substrate for lack of an alternative. Cohabitation is conditional: single housing is safest for guaranteeing feeding and injury monitoring, and while same-sex or mixed-sex groups can work in large, heavily planted enclosures with multiple feeding and hide stations, males must never be housed together and an unplanned mixed-sex group carries a real breeding risk. A new animal, or one returning from a show or vet visit, belongs in a simple separate quarantine enclosure — bare-bottomed or paper-substrate, with its own hide and dishes, away from established collections.

Heating, Lighting and Humidity

Target a basking surface temperature of 80–83°F (27–28°C) directly under a low-output basking bulb or high-output LED, measured with an infrared temperature gun or a probe thermometer resting on the actual perch surface, not the surrounding air, and never let any point in the enclosure exceed 85°F (29°C). This species survives without a basking source, but providing one supports natural thermoregulatory behaviour and lets UVB do its job. Air temperature is a separate measurement and should be taken with a digital thermometer or thermostat probe positioned at the animal's level: warm-side air should read 74–78°F (23–26°C), cool-side air 68–72°F (20–22°C). A night drop in air temperature to as low as 65°F (18°C) is safely tolerated and is beneficial rather than merely acceptable — it mimics the natural diel cycle and does not need extra heating to prevent it in most homes.

Any heat source strong enough to reach the basking figure above should run on its own thermostat, with the probe taped to the basking surface itself, not floating in the air or against the heat emitter, so the controller regulates what the animal actually contacts.

UVB Provision

UVB is increasingly recommended for this species even though it is not required for survival if dietary D3 is provided through supplementation. The target is 0.5–1.0 UVI at the basking site — low-end Ferguson Zone 1 — delivered by a low-percentage T5 tube (2.0–5.0 UVB output). Achieving that index depends on lamp distance and any mesh between the lamp and the animal, both of which attenuate output substantially; measure the actual UVI at the basking perch with a properly calibrated UV meter and adjust distance rather than assuming a bulb's rated percentage translates directly to the reading at the perch. A 12-hour photoperiod on a timer, shortened modestly in winter and lengthened in summer, is a reasonable default in the absence of species-specific photoperiod research.

Humidity Cycling

Daytime humidity should sit at 50–60%, with a nightly spike to 70–80% driven by an evening misting, then allowed to dry back down before the next misting rather than kept permanently saturated. Measure it with a digital hygrometer placed at mid-height in the enclosure, not pressed against the glass where condensation skews the reading. Misting by hand or an automated system both work; the failure mode to watch for is a substrate that never dries between mistings, which invites mould and bacterial growth rather than helping the shed cycle it is meant to support.

Substrate, Decor and Enrichment

A coco-fibre or coco-fibre/sphagnum moss blend, or a bioactive mix with a live clean-up crew, both hold the daytime-to-nighttime humidity swing well and support the digging a gravid female needs for a lay-box — provide at least 4 in (10 cm) of moist substrate depth in a dedicated lay area for a breeding or gravid female. Paper towel is an acceptable, if unattractive, alternative for a quarantine or hospital setup where humidity control and easy waste-spotting matter more than aesthetics.

Loose substrates marketed as sand or fine calcium-sand blends are not recommended: ingested particles picked up while licking food or drinking off the substrate surface can accumulate in the gut over time, and there is no husbandry advantage a safer substrate does not already provide. Undiluted garden soil or unrinsed bark chips carry a pesticide or mould risk not worth taking with a captive-bred, readily available species.

Because this is an arboreal animal, decor should be vertical-first: cork bark rounds and flats, sturdy branches set on the diagonal, and dense artificial or live foliage (pothos, ficus and sansevieria all tolerate the enclosure conditions this species needs) to create visual barriers the animal can retreat behind. Bioactive setups suit this species well given the humidity range it already needs and the relatively light bioload of a single gecko. Rotate enrichment modestly — repositioning branches, adding a new climbing route, varying feeding location — every few weeks; a habitat that a keeper can rearrange gives an active climbing species more of its natural repertoire to use.

Feeding, Supplements and Hydration

Commercial crested gecko diet (CGD) powder mixed with water is the staple and is nutritionally complete on its own — it does not need a separate calcium or vitamin dusting the way feeder insects do. Gut-loaded crickets and dubia roach nymphs, offered as an occasional rotation rather than the staple, add valuable enrichment and protein diversity; insects should be sized no wider than the gap between the animal's eyes at minimum, scaling up with age, so an oversized cricket never becomes a regurgitation or impaction risk.

Every feeder insect should be gut-loaded in the 24 hours before feeding and then dusted with calcium and D3, on the frequency set out by life stage; a plain calcium dusting on off-insect weeks and an occasional multivitamin dusting cover any gap left by a diet that is not exclusively CGD-based. A shallow water dish should always be available even though most hydration in practice comes from misting droplets on leaves and enclosure surfaces, which this species is adapted to drink from rather than a still dish.

Body condition is judged at the tail base and hips: a healthy adult carries a full, rounded tail base with the hip bones present but not sharply visible under the skin. An overweight crested gecko shows a tail base wider than the body directly in front of it and a visibly rounded, saggy abdomen even at rest — reduce insect frequency and portion size, and check that CGD is not being left available continuously, before assuming anything more serious.

Daily, Weekly and Monthly Care

Realistic daily care for one crested gecko in a correctly set-up enclosure takes five to ten minutes: a misting session, a quick food check, and a glance at both thermometers and the animal itself. The habit most likely to slip is removing uneaten CGD before it sours rather than topping fresh food onto old — stale diet powder left in place for days is the single most common daily-care shortcut that quietly damages appetite and hygiene.

Weekly tasks add up to closer to twenty minutes and are the ones most often skipped under time pressure: a live insect feeding, a wipe-down of glass or PVC panels, and a body-condition check are all easy to defer by a day or two, but deferring the insect feeding repeatedly is how a calcium-D3 shortfall builds silently over months. Monthly care — a substrate deep-clean, checking UVB bulb age against its replacement schedule, and reviewing feeding and weight records — is the layer keepers most often forget, because nothing looks visibly wrong day to day; a UVB tube can lose most of its usable output well before it visibly dims, which is exactly why tracking install date rather than appearance matters.

Handling and Behaviour

Give a newly acquired crested gecko a settling-in period of undisturbed husbandry-only contact before any handling begins — feeding, misting and cleaning around the animal without picking it up lets it learn the enclosure and the keeper's presence are not threats. Once handling starts, pick the animal up by letting it walk onto an open, flat hand or a low, soft surface rather than grasping from above or around the body, which reads as a predator strike to a prey species.

Ten to fifteen minutes is a realistic session length, and daily handling is unnecessary — a few sessions a week is enough to keep an animal comfortable with contact without adding chronic stress. Normal body language is calm, deliberate movement and a relaxed, level tail; stress signals include rapid darting, tail-waving or vocalising squeaks, and a hunched, tucked-in posture. A defensive bite from this species is rarely more than a pinch and does not typically break skin; the behaviour to actually protect against is the jump-and-drop response under sudden movement or a tight grip, since a dropped tail does not regrow.

Sessions with children should be seated, over a low surface, and directly supervised throughout — not because the animal is aggressive, but because a startled crested gecko moves faster than most children can react to, and an open doorway or gap in enclosure furniture is all it takes for an escape. Keep enclosure doors, vents and any access point secured with a functioning latch, since this species is a capable climber and an efficient escape artist given any opportunity.

Health and Veterinary Care

Any newly acquired animal warrants a hands-on check before it goes anywhere near an established collection: clear, fully open eyes, an even gait with no dragging limb, a straight jawline, and a body with visible but not sharp hip bones. A quarantine period in a separate, simply furnished enclosure — commonly run for several weeks to a few months in general reptile-keeping practice — lets a keeper watch for problems that were not obvious at the point of sale before any shared airspace or equipment is introduced.

Normal droppings are a firm, dark, formed stool alongside a white-to-cream urate portion; watery stool, a green or unusually pale urate, or a sudden change in frequency are all worth tracking against feeding and temperature records rather than dismissed as one-off. Sheds should come away in reasonably large pieces given adequate nightly humidity; small, retained fragments around the toes or tail tip point to a humidity shortfall rather than a health problem in themselves. Weighing a juvenile or breeding female periodically and logging the number is a more reliable early-warning system than eyeballing body shape from memory.

The husbandry-linked conditions actually seen in this species trace back to a short list of causes: metabolic bone disease from inadequate calcium and D3 relative to UVB provision, respiratory infection from chronically cool, damp, poorly ventilated enclosures, and retained shed from humidity that never reaches the nightly target. None of these are treated at home — a soft or rubbery jaw, bowed limbs, open-mouth breathing or audible clicking, unexplained weight loss, or any sign of prolapse all warrant an exotics vet, not a home remedy. A seller's store page or the general care guide index are useful for husbandry review beforehand, not for the medical question itself.

Buying This Species

Every crested gecko reasonably available for purchase today is captive-bred; wild collection from New Caledonia has been prohibited for close to two decades, and a genuine wild-caught animal would be both exceptionally rare and illegal to have exported. That makes lineage a straightforward question to ask a seller rather than a grey area to navigate, and it is worth asking regardless — a seller who can speak plainly about a hatch date and parentage is a good early signal.

A healthy animal photographs with clear, fully domed eyes, an even skin tone with no retained shed patches, and a tail base proportionate to the body — avoid anything shown with a visibly kinked spine, a lopsided jaw, or a tail base disproportionately thin against the hips. In hand, a healthy crested gecko grips firmly, moves with intent rather than dragging, and reacts to a light touch with normal alertness. One line-specific concern worth naming honestly: some lily white bloodlines have a reported association with neurological head-tilt and imbalance issues; this is not universal to the line and the evidence is more anecdotal than formally studied, but it is worth asking a breeder about directly rather than assuming every animal marketed under that name is unaffected.

Arrange transport for the cooler part of the day where possible, and have the enclosure fully set up and stable at target temperature and humidity before the animal arrives, so it goes straight into a working environment rather than a construction site. Use the seller's health checklist and any records offered — hatch date, feeding history, prior shed dates — as a starting reference for the quarantine log rather than a one-time formality. Sellers with an established track record are easiest to find by browsing verified stores directly, and current availability for the species can be checked any time through the crested gecko listings on the marketplace.
