A hardy, arboreal New Caledonian gecko named for the horn-like cranial bumps over its eyes, popular for its calm nature and tolerance of room-temperature housing.

Part of the Geckos
Geckos range from desert ground-dwellers to humid cave and forest specialists; eyelid geckos like Goniurosaurus and leopard geckos have movable eyelids and are largely terrestrial.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Arboreal terrarium
18 × 18 × 24 in (≈ 30 gal)
An adult gargoyle gecko needs an 18×18×24 vertical terrarium with cork branches, foliage, and a humidity range of 50–70%. Ambient 22–26 °C — no basking lamp typically needed.
Recommended
Planted vertical vivarium
24 × 18 × 36 in, planted
A taller planted vivarium with varied climbing branches, live plants, and multiple feeding ledges. Low UVB (3–5%) supports natural cycles. Mist nightly to 80% then let dry.

Bioactive arboreal enclosure
36 × 18 × 36 in, bioactive
Bioactive planted enclosure with deep substrate, springtails/isopods, dense foliage, and varied vertical structure. Closely mirrors New Caledonian shrub habitat.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg / Neonate
Most reptiles lay leathery- or hard-shelled eggs incubated by ambient warmth, though some snakes and lizards give live birth. Incubation temperature can influence sex and development in many species.

Hatchling
Hatchlings emerge as fully formed miniatures of the adult, often using an egg tooth to slit the shell. They are independent from birth but small and vulnerable, and may show brighter or different juvenile patterning.

Juvenile
Juveniles grow steadily, shedding their skin periodically as they enlarge. Coloration and proportions shift toward the adult form, and growth rate depends heavily on temperature, diet, and basking/UVB access.
Adult
Adults reach the species' full length and mass and become sexually mature. Many reptiles show sex differences in size, coloration, or features (such as larger heads, hemipenal bulges, or femoral pores), and continue to shed throughout life.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
House a single adult in a vertically oriented terrarium of at least 18 x 18 x 24 in (45 x 45 x 60 cm); juveniles can start smaller to help them find food. Furnish densely with cork bark, branches, vines, and broad-leaved (live or artificial) plants so the gecko can climb and hide off the floor. A moisture-retaining substrate such as coco fiber or a bioactive soil mix supports the ambient humidity these geckos need.
Gargoyle geckos thrive at relatively cool temperatures: a daytime range of about 72-80F (22-27C) with a cool-side gradient and a nighttime drop into the high 60sF. Sustained temperatures above the mid-80sF are dangerous. As a nocturnal species they do not require UVB, but low-level UVB (around 5%) is beneficial. Maintain humidity around 50-70% by misting once or twice daily, allowing the enclosure to dry out partly between mistings to prevent stagnant, mold-prone conditions.
Substrate
A moisture-holding bioactive mix (coco fiber, soil, leaf litter over a drainage layer with springtails/isopods) maintains humidity well; paper towel works for quarantine or hatchlings, while plain coco coir is a simple, reliable choice.
Equipment & setup
Provide a tall, ventilated terrarium (18x18x24 in for an adult) furnished with cork bark, branches, and foliage for climbing. They do best at 72-80°F (avoid sustained heat above ~82°F), generally need no supplemental heat indoors, and benefit from low (5%) UVB plus evening misting to keep humidity around 60-75% with nightly drying.
Diet
Easily maintained on a complete powdered diet (such as Pangea or Repashy crested/gargoyle gecko meal replacement) mixed with water and offered in a shallow ledge dish 2-3 times per week. This species is more carnivorous than the related crested gecko and readily takes appropriately sized live insects (crickets, dubia roaches) as enrichment and extra protein, dusted with calcium and a multivitamin.
Occasional pureed fruit can be offered as a treat but should not replace a balanced commercial diet. Provide fresh water in a shallow dish and through misting droplets, which many individuals prefer to drink from.
Behavior & temperament
Generally calm and tolerant of brief, gentle handling, though individuals vary and some are more flighty. They are nocturnal and arboreal, spending the day tucked among foliage and becoming active at dusk. Unlike crested geckos, gargoyle geckos can regenerate a lost tail, but dropping it is still stressful, so never grab or restrain by the tail.
Provide vertical climbing structure, multiple sight-broken hiding spots, and varied perch diameters for enrichment. House adults singly: they can be cannibalistic toward smaller individuals and males are territorial, so cohabitation risks injury.
Health
With good husbandry this is a robust, long-lived gecko. The most common problems are heat stress from temperatures that are too high, metabolic bone disease (floppy tail or jaw deformities) from inadequate calcium and D3, and retained shed on toes from low humidity. A cool, well-ventilated, appropriately humid enclosure prevents most issues.
Watch for weight loss, mouth rot (stomatitis), and impaction if loose substrate is ingested with food. A reptile veterinarian should evaluate any animal with persistent inappetence, swelling, or a kinked spine; periodic fecal screening for parasites is wise, especially after acquiring a new animal.
Tips, DIY & hacks
Closely related to crested geckos, gargoyles thrive on the same powdered complete diets (Pangea/Repashy), so live insects are optional enrichment rather than a requirement. They can be cannibalistic and territorial — house singly or as established pairs and never keep two males together; unlike cresteds, their tails regenerate.
