Lygodactylus williamsi, commonly known as William's Dwarf Gecko or the Electric Blue Gecko, was first discovered by biologist William in the 1950s.

Found in the Kimboza Forest in eastern Tanzania. This tropical forest habitat is rapidly shrinking due to deforestation.

Description

Males are bright blue with heavy black throat stripes, and visible preanal pores and hemipenile bulges. The females range from brown or bronze to bright green, and have little to no black on their throat. Females can easily be confused with juvenile or socially suppressed males that are also green, sometimes with a blueish cast. The underside of both sexes is orange. Colors of individuals vary according to mood and temperature—males may range from black or gray to brilliant electric blue. Females may range from dark brown to brilliant green with turquoise highlights. Adult snout-vent length is 5 to 8 cm.

Natural Food

This gecko eats small insects and drinks water from leaves. They are also fond of nectar.

Behavior

Like all Lygodactylus and Phelsuma genus geckos, this species is diurnal. L. williamsi are bold, active, social, and males are territorial. Social gestures include lateral flattening, puffing out of the throat patch, head shaking and head bobbing, and tail-wagging.

Reproduction

Males court females with lateral flattening, puffing out of the throat pouch, and head bobbing. Two to three weeks after copulation, the female lays a clutch of 1 or 2 pea-sized white, hard-shelled eggs which are glued to a surface in a secure, hidden location. Eggs hatch in 60 to 90 days.

In Captivity

These tiny lizards are generally housed in planted tropical vivariums or vertical (tall) terrariums. Provided with UV-B (mid spectrum) light and an (UV-A) basking spot , daytime temperatures of 75.2F (24.0C) to 86F (30.0C), and night-time lows of 64.4F (18.0C) to 71.6F (22.0C), they have proven to be fairly hardy. Humidity should range from 50% to 85%.

Misting twice a day provides water for drinking, but these geckos have also been seen frequently drinking from small cups or from bromeliad bases. They will eat a wide variety of insects including fruit flies, mini-mealworms, phoenix worms, small silkworms, roach nymphs, and crickets up to 1/4" in size. Daily supplementation of insects with Phosphorus free calcium and vitamin supplements is vital. Supplemented fruit puree or a commercial MRP (meal replacement powder, which is prepared with water) made for crested geckos or day geckos is readily accepted. Food offerings must be limited to avoid obesity, and feeding 3 times per week is sufficient when using MRP's.

Only one male should be housed per group, to avoid dangerous aggression. Multiple feeding stations will help to avoid excessive aggression between females.

These geckos breed readily in captivity, when they are satisfied with their environment and properly cared for. The eggs can be hatched in an incubator or in the enclosure. Incubated eggs hatch in about 80 days at 27 degrees Celsius. Eggs left in the enclosure will hatch in about 100 days. It takes longer because of the fluctuating temperatures at day and night. But the hatchlings are often stronger. Glued eggs should best be left inside the terrarium, because they could crack while removing them. But be aware of predators (like their parents!) when hatched, so gently remove them as soon as possible to a new environment. Best use relatively large enclosures like 15x30x30 cm in size, with 2-3 hatchlings per enclosure.


These small geckos are remarkable for their virtually fearless nature, and quickly tame. Handling is not recommended for such small animals, but they can be lured onto their keeper's hands with insect treats, and will remain active and behave naturally while being observed, once they are acclimated to captivity (often as quickly as one month after introduction to their enclosure).
