Species group: Geckos
Other common names: Giant Gecko; Leach's Giant Gecko; Grande Terre Gecko
Scientific name: Rhacodactylus leachianus leachianus
The Grand Terre Giant Gecko is one of two sub-species of New Caledonian Giant Gecko (leachianus). It is a nocturnal, arboreal species of gecko which makes its home in the highest treetops on the island of Grande Terre in New Caledonia. The other sub-species, the Henkel's Giant Gecko (Rhacodactylus leachianus henkeli), is smaller, and is found on offshore islands of New Caledonia.
Appearance / health:
The Grand Terre Giant Gecko can reach 14 inches (360 mm) total length, and is one of the largest geckos in the world, if not the largest.
New Caledonian Giant Geckos are arboreal, and strongly prefer a cage that is taller than it is long. A single adult gecko can be housed in an enclosure that is 3 feet long X 2 feet deep X four feet tall. Males should never be housed together. Room temperature of 65- 80 degrees F is suitable.
In the wild this gecko is omnivorous and feeds on insects and fruit and will also occasionally eat smaller lizards. In captivity they thrive on a varied diet including mealworms, waxworms, crickets, fruit and meat baby food, small lizards/ pinky mice, and a commercial product such as Giant Gecko Meal Replacement Powder (MRP).

The World's Most Spectacular Gecko
Stoutly-built and nearing 18 inches in length, these largest of the world’s geckos caused quite a sensation when they first appeared in the pet trade. Although not a beginner’s pet, with proper care these magnificent geckos do quite well, living into their 20’s and breeding regularly.
Shy and completely arboreal, Grand Terre giant geckos should be kept in terrariums which are vertically oriented and well-stocked with vines, cork bark rolls (these are essential hiding places) and sturdy plants. A single adult requires an enclosure the size of a 55 gallon aquarium, at minimum. Pairs may co-exist, in larger quarters, but must be watched carefully.
They are nocturnal, and so if provided a healthful diet and ample Vitamin D3 will do fine without UVB exposure. Red reptile night-viewing bulbs will allow you to watch your pets after dark (they sense little if any of the light produced by these bulbs), and can also be used to supply an ambient temperature range of 76-85 F. Humidity must be kept high – to 75-80% - but the tank should be allowed to dry out by day. Moist coco-husk and sphagnum moss and, in dry homes, a reptile humidifier, will assist in maintaining the conditions they favor.
A wide variety of insects supplemented with powdered calcium and vitamins are essential to your gecko’s well-being. Roaches are a particular favorite, and a steady supply should be in place before you purchase a Grand Terre giant gecko. Crickets, silkworms, hornworms, locusts and other commercially-available insects should also be supplied; crickets and mealworms alone, even if supplemented, will not maintain their health long-term. About a third of the diet should consist of commercial nectar mixes sold for use with crested and day geckos (Phelsuma spp.); a homemade slurry containing fruit, baby food, calcium powder and honey should also be provided. A pink mouse may be offered at 6-8 week intervals..
