Crested gecko

Build around climbing and quiet observation

Provide a tall, well-furnished home with sheltered routes and accessible feeding ledges. Correlophus ciliatus is the crested gecko of New Caledonia; older resources use Rhacodactylus ciliatus. Other New Caledonian geckos have their own requirements. Expect much of its activity after dark.

An adult with an intact tail is commonly around ≈ 7.874″ (20 cm) long. Plan for roughly 15–20 years of care, including hot-weather management and a reptile-veterinary reserve. This suits a keeper who enjoys observing a climbing animal and can check it daily, rather than someone seeking frequent handling.

Choose usable height and horizontal space

We recommend a minimum usable internal enclosure of 18″ × 18″ × 3′ (about 46 × 46 × 91 cm), length × depth × height, for one adult. Prefer 2′ × 2′ × 4′ (about 61 × 61 × 122 cm) when possible. Internal height includes substrate: a 2″–4″ (5–10 cm) layer leaves about 32″–34″ (81–86 cm) before any separate drainage layer. Deduct that layer too when checking the space left for climbing and safe lamp clearance.

House one gecko. A larger box does not make a group safe or establish a need for companionship. The floor still matters: the animal needs sideways routes and resting choices, not only a narrow upright shaft. Doors, mesh and cable gaps must contain its current size.

Make food, water and shelter reachable

Anchor branches and broad resting surfaces at several heights, with cover connecting warm and cool areas. Include horizontal rests and routes to the floor. Test every attachment and remove trapping gaps. Keep hot fittings out of reach.

Place a secure feeding ledge beside a familiar covered route. For a small juvenile, add suitably narrow branches, close cover and easy access to food and water. Move or expand housing according to access, growth and measured conditions; a particular gram weight is not a biological deadline. Recheck heat and UVB whenever housing changes.

Measure the air where the gecko rests

Aim for daytime air of 79–82°F (26–28°C) by an upper occupied perch and 68–75°F (20–24°C) in a shaded lower retreat. Use 64–68°F (18–20°C) as a night-drop reference with lights off, without forcing an otherwise suitable room colder. These are our local-air implementation of RSPCA’s temperature zones, whose original wording does not explicitly identify air versus surface.

Use independent digital probes beside the perch and lower retreat, shielded from direct lamp heating and not touching a warmed branch. Check reachable surfaces separately with an infrared thermometer. We have not established a numerical surface optimum for this protocol; do not apply the air targets to an infrared reading.

References: [1]

Plan for the hottest afternoon

Control any heater with a compatible thermostat, secure the control probe according to its instructions and guard hot fittings. Verify the result independently, including the coolest retreat. Moving a branch can change the animal’s heat exposure even if the thermostat setting stays the same.

Record summer room temperatures and arrange effective room cooling or a secure cooler location before a heatwave. A thermostat can stop heating but cannot cool hot air. Do not use a published maximum as permission to keep the whole enclosure close to it. No universal chronic heat-injury boundary is established here.

Provide gentle UVB with deep shade

Provide about UVI 0.7 at head height on the closest reachable exposed position, with deep shade approaching zero. Measure the actual installation, including mesh and branches. Check the roof if the gecko can reach it. A bulb percentage or distance alone cannot verify exposure.

Set 12 hours of daytime light and 12 hours of darkness for ordinary pet maintenance. Keep the vitamins and vitamin D3 already included in its complete food. A gecko with eye, skin or other health concerns needs an individual plan; do not invent a different UV dose solely from a morph name.

References: [1] [8]

Mist, allow drying and provide drinking water

Let humidity rise around 60–80% after misting and fall toward 40–50% before the next cycle. Measure with a shielded digital sensor away from direct spray and note the local temperature. A middle-height sensor is our practical reference position; inspect wetter sheltered areas as well.

Adjust misting and ventilation to the actual room and enclosure. Surfaces should dry between cycles without leaving the animal dehydrated. Misted droplets provide drinking opportunities, and a shallow accessible dish must also stay filled with clean water. Change it daily and whenever soiled.

References: [3] [1]

Keep the floor maintainable

For an established naturalistic setup, start with 2″–4″ (about 5–10 cm) of suitable soil/coir substrate, with leaf litter and drainage as needed. This practical moisture-management layer is not a proven optimum or a universal female nesting depth. Count it within the enclosure’s internal height.

Paper can simplify juvenile, arrival or illness observation. Whichever floor you use, keep feeding surfaces clean and leave access for waste removal and drainage maintenance. Plants and clean-up organisms do not eliminate servicing. A mature female needs a private usable digging site as well.

References: [4] [10]

Use a complete diet as the staple

Choose a product explicitly formulated as a complete crested-gecko diet. Keep the familiar formula during arrival, then follow the exact product’s preparation and life-stage directions. Fruit purée, baby food and insects alone are not interchangeable complete staples.

We recommend a complete formula as the foundation rather than the fruit, insect and diet rotation still found in some guidance. Ingredient bans applied to whole foods do not establish that a formulated food containing those ingredients is unsuitable. Product labels define the intended use; they do not prove every formula has identical nutrition or feeding directions.

References: [5] [6] [1]

Pangea with Insects: follow this formula’s directions

For Pangea Gecko Diet with Insects, start with one part powder to two parts water and adjust consistency. The online directions do not specify mass or volume, so use the current packet or obtain manufacturer clarification instead of inventing a gram conversion. The label’s growth option is daily feeding; adult maintenance is three to five feeds a week. Separate insects are optional.

Keep clean prepared mixture refrigerated for no longer than the label’s seven days. Used enclosure cups are different: remove food within 24 hours as our routine, sooner if soiled, spoiled or the current label is stricter. Never return leftovers to stored food. Check current expiry and storage directions for powder.

References: [5]

Repashy Banana: keep the mixing rules separate

For Repashy Crested Gecko Diet: Banana, mix one part powder with two parts water by volume. Allow it to thicken, then adjust consistency under its instructions. Offer it in the evening and remove uneaten food within 24 hours. The label allows voluntary access rather than specifying a fixed gram ration.

Prepare small fresh portions unless the manufacturer supplies a storage period for this particular slurry. Do not transfer Pangea’s seven-day refrigerated limit or maintenance schedule to this formula. Monitor actual intake and body condition whichever food you choose.

References: [6]

Keep supplements tied to the whole diet

Optional captive-produced insects can provide hunting opportunities. Offer small, manageable prey and remove leftovers. Feed and hydrate the insects appropriately beforehand. Account for these meals in total intake rather than adding unlimited extras to complete food.

For a healthy gecko eating complete food under the measured UVB setup, a practical separate-insect option is a light, even coating of PangeaCal without D3 immediately before feeding. Leave the complete food’s vitamins and D3 intact and do not routinely add more powder to it. If UVB is unverified, growth is poor or a female is laying, review the whole plan individually rather than stacking products.

References: [7] [8] [1]

Watch the trend in intake and weight

A small gecko may leave very little visible food missing. Check whether it reaches the cup, look for droppings and weigh it under comparable conditions. Record the trend alongside growth and body condition. One apparently untouched meal is less informative than repeated poor intake or weight loss.

Adjust portions as growth slows. There is no universal ideal weight, insect count or safe fasting duration for every individual. Seek veterinary advice for persistent loss of appetite, declining weight or poor growth rather than cycling through foods and supplements without identifying the problem.

References: [12] [9]

Support the body and expect jumps

Let a settled gecko step onto a supported hand where possible, close to a soft surface in a secure area. Keep interactions brief and stop when it repeatedly tries to escape. Never restrain it by the tail. Necessary care should remain calm even for an animal that dislikes optional handling.

Crested geckos do not regrow a lost tail. An established tailless adult still needs the same climbing choices and is not automatically in need of extra food. Fresh tail loss, a wound or a change in grip deserves attention to health and enclosure safety.

References: [1] [12] [13]

Inspect toes, eyes and grip

Check for retained material around toes, the tail tip and eyes after shedding. Tight rings, swelling, repeated retention or reduced use need veterinary advice. Review the moisture cycle and hydration, but do not peel skin or force baths as a default response.

Weakness, altered grip or unusual posture is not a diagnosis. Provide horizontal resting choices and record when the change began, food and supplement use, weights and environmental readings. Do not infer a calcium dose from a photograph or a tail shape.

References: [9] [12] [13]

Give a mature female a private laying site

A female may produce eggs without a current male. Provide an accessible, secluded area of moist material that she can excavate fully, with enough room to enter, turn and dig. General reptile veterinary guidance supports privacy and suitable substrate, but does not establish one universal crested-gecko nest depth.

Discuss reproductive and nutrition concerns with a reptile veterinarian. Persistent straining, swelling with appetite loss or weakness needs prompt assessment; prolapse is urgent. Do not manipulate eggs, force the mouth open to inspect calcium stores or add an arbitrary calcium percentage to every meal.

References: [10]

Prepare a functional separate arrival habitat

Obtain the animal’s identity, origin, familiar food and recent weight and health history. Arrange an initial reptile-veterinary examination within two weeks and ask about appropriate screening. Where other reptiles are present, use separate housing and dedicated equipment.

A simpler arrival enclosure still needs climbing, cover, temperature choices and accessible food and water. Leave optional handling until the animal is feeding and settling. A fixed number of days or a single negative test does not establish freedom from infection.

References: [9]

Clean food, water and soiled surfaces daily

Remove old food, refresh drinking water and deal with waste daily. Plan deeper cleaning around actual soiling and the substrate system. Keep secure temporary housing available for major work, and remove physical dirt before following disinfectant instructions.

Use dedicated tools away from kitchens and food preparation. Wash hands with soap and water after touching the gecko or its supplies. Reptiles can carry germs while looking healthy; CDC (Centers for Disease Control and Prevention) advises against reptiles in households with young children, adults 65 or older, or people with weakened immunity.

References: [11] [1]

Get help for persistent or serious changes

Contact a reptile veterinarian for continuing appetite or growth problems, weight loss, abnormal stools, swellings, repeated retained shed or a sustained change in grip. Bring food labels, supplement details and your environmental and weight records.

Breathing difficulty, marked weakness, major injury, inability to move normally or prolapse needs urgent advice. Keep the animal secure while arranging care. Do not force-feed, medicate or improvise calcium treatment. Correcting a setup problem and obtaining medical assessment may both be necessary.

Where recommendations differ

RSPCA gives ≈ 17.8″ × 17.8″ × 23.7″ (45 × 45 × 60 cm), length × depth × height, while ReptiFiles opens with 18″ × 18″ × 3′ (about 46 × 46 × 91 cm) and later lists some shorter products. We select the taller authored reference for connected climbing and environmental choices. These are practical recommendations; a controlled study has not established the exact minimum.

ReptiFiles also recommends an upper temperature of 82–84°F (28–29°C) and UVI 1–2, compared with the RSPCA-based plan used here. These differences do not justify averaging targets. We retain the previously selected lower-exposure pet protocol with deep shade and clear measurement methods. A different coherent plan may be appropriate with competent assessment of the actual installation and animal, particularly when health or lighting sensitivity changes the requirements.

Test the furnished home before collection

Gather the secure enclosure, anchored branches and cover, accessible ledges, water dish, substrate and drainage access. Add independent air probes, an infrared thermometer, a hygrometer, suitable UVB and access to a UV Index meter, a timer and compatible control for any heater.

Run the finished empty habitat through at least a week of day and night checks as our preparation routine. Record air and surface checks separately, humidity rise and drying, UVI and shade, access and security. Include warm-room conditions and retain a seasonal recheck plan. Budget for complete food, service supplies, replacement equipment and veterinary care, and train a substitute caretaker.
