Species description
Geographical Origin and Habitat: Endemic to the dense tropical primary rainforests of the New Caledonia archipelago in the South Pacific, specifically the island of Nuu Ami. It spends its life in the high canopy, camouflaging on mossy tree trunks and sheltering in natural hollows of old-growth trees during the day.
Taxonomy and Genetics: A massive, heavy-bodied gecko reaching up to 25-30 cm in length. It features loose, folds of skin along the body that aid in camouflage and air gliding. The Nuu Ami locale is highly patterned, displaying bark-like grey, green, and brown base colors decorated with bright peach, salmon-pink, and mustard-yellow spots.
Behavior and Habits: Strictly nocturnal and arboreal. Highly territorial. They communicate through vocalizations, producing barks, clicks, and deep growls at night. They are highly intelligent and often show strong pair-bonding behavior with their mates.
Morphology: Females are slightly smaller than males. Males are larger, possess wider head structures, visible preanal pores, and a prominent hemipenal bulge at the base of the tail.
Care, breeding and tankmates
Terrarium Setup: Requires a very large, vertical, and sturdy enclosure (minimum 60x45x90 cm for an adult). Provide thick vertical and diagonal cork bark tubes and sturdy branches (as thick as a human arm). Use a moisture-retaining substrate such as coco fiber and peat, and furnish with large-leaved live or synthetic plants.
Lighting and Heating: Subtropical species that prefers moderate temperatures. Maintain daytime temperatures between 22°C and 26°C. Avoid temperatures above 28°C, which can cause fatal heat stress. Provide low-level UVB light (Arcadia ShadeDweller 5% or equivalent) for skeletal health.
Humidity and Hydration: Maintain high humidity levels (60-80%) through regular evening misting. Good cross-ventilation is essential to prevent respiratory infections. The gecko will drink water droplets from the glass and bark.
Feeding and Supplementation: Omnivorous and frugivorous. The primary diet (70%) should consist of high-quality powdered gecko diet (Repashy/Pangea) mixed with water. Supplement once a week with large crickets or Dubia roaches dusted with calcium and D3.
Compatibility: Highly territorial. Can be kept in breeding pairs, but bonding must be monitored closely as incompatible pairs can fight to the death. Never house multiple males together.
Health and Common Diseases: Vulnerable to metabolic bone disease (MBD) if calcium and D3 are lacking. Sensitive to respiratory infections caused by stagnant air and constant wet conditions. Tail loss (autotomy) can occur under severe stress; the tail will not regenerate.

The catalog's scalar value is 28 cm. The ReptTraits v1.2 source reports a maximum adult measurement of 28 cm for this species, recorded as snout–vent length (SVL). These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
