Lygodactylus williamsi
A small gecko of 7-9 cm in which adult males turn a brilliant turquoise blue. Endemic to a very small area of forest in Tanzania and found nowhere else, it is listed as Critically Endangered by the IUCN and is a species for experienced keepers.
Lygodactylus williamsi is a diurnal gecko of the family Gekkonidae endemic to a very small area of forest in eastern Tanzania. It is small at 7 to 9 cm and strongly sexually dimorphic: dominant adult males are a brilliant turquoise blue over the whole upper surface, with a broad black streak running from the nostril through the eye to the nape, while females and subordinate males remain greenish brown. In the wild it lives exclusively on the screwpine Pandanus rabaiensis, in the leaf crowns of large trees whose leaves exceed a metre in length; a single leaf crown typically holds one animal, or an adult pair with juveniles. It eats small insects and fruit, drinks water from the leaves and is fond of nectar. Its range covers only about 8 square kilometres at 170 to 480 m. Illegal collection for the international pet trade is the greatest threat, and habitat destruction follows from it, as collectors fell the screwpines to reach geckos in the leaf crests. The IUCN lists it as Critically Endangered, with the population thought to be declining rapidly.

Listed under Washington Convention Appendix I as of January 2, 2017. It qualifies as an internationally rare wild animal or plant species under the Act on Conservation of Endangered Species of Wild Fauna and Flora, and a registration certificate for each individual is required for domestic transfer or equivalent transactions. Sale or transfer of individuals without a registration certificate constitutes a violation of the Act. It is neither listed as a specified animal under the Ordinance for the Enforcement of the Act on the Welfare and Management of Animals, nor designated as a specified alien species under the Invasive Species Act.

Size

Humidity

Fruit flies, micro crickets and other small insects, plus nectar and fruit
Create a localised basking spot of 32-35C, with the top of the enclosure at 27-29C and daytime ambient at 24-27C. Simply switching off heat and lights lets the temperature fall to 16-26C overnight, which is fine. Hold humidity at 60-80 per cent, keeping the floor more humid than the top. Rising to near 100 per cent after lights out is harmless, but because the gecko is so small, dry conditions dehydrate it rapidly.
A tall front-opening enclosure of about 30 x 30 x 30 cm, roughly 8 gallons, is the usual guide for one adult. Reproduce the screwpine leaf crown with slender leaves and vertical branches set at several heights so the gecko can choose its temperature. Lay 5 to 8 cm of moisture-retentive substrate and plant live plants watered several times a week to stabilise humidity. It is tiny and escapes easily, so watch every gap around openings.
It takes nectar and fruit as well as insects. Its very small size makes finding suitably sized prey a challenge, so provide fruit flies and micro crickets that fit its mouth, optionally alongside a prepared fruit-based gecko diet. Dust feeders with calcium.
It is diurnal, and well-coloured males perch conspicuously, but it is too small and delicate for handling. Males fight fiercely and must not be housed together. In the wild each leaf crown holds one animal or a pair, so keep it singly or in pairs.
It has been listed on CITES Appendix I since 2 January 2017. Under Japan's Species Conservation Act it is an internationally endangered species, and transferring one within Japan requires an individual registration certificate; trading or transferring an unregistered animal breaches that Act. It is neither a specified animal nor an invasive alien species under Japanese law. Its eggs show temperature-dependent sex determination, with daytime averages of 21-24C producing females, 26-27C producing both sexes and 28C or above producing males, hatching in 60 to 120 days. Captive breeding does occur, but rearing the young is demanding and no large-scale production is established. Illegally wild-caught animals have been reported sold as captive-bred, so always check the registration certificate and the origin.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
