Distribution and habitat

The crepuscular to nocturnal marbled geckos are particularly widespread in southern Vietnam. There they inhabit the dense treetops of the rainforests as well as richly structured rock biotopes and can also be found as cultural successors near settlements.

Maintenance

Minimum dimensions for the terrarium, according to the size and number of animals

1-2 animals

6KRL x 6KRL x 8KRL (L x W x H)

Head-torso length (KRL) is measured on the largest animal. For each additional animal, increase the footprint by 15%. A terrarium of e.g. 80 x 80 x 110 cm is recommended, which should be placed in a quiet and vibration-free place

You need a terrarium with strong climbing branches, many plants (ficus, ferns, mosses, epiphytes, etc.), rock formations (hiding places and privacy screens), structured back and side walls (e.g. cork lining) and a substrate of forest soil-peat mixture as well as a large water basin (waterfall). Several times a day the inside of the terrarium should be finely sprayed with water (humidity), but a rain or mist system is better

Temp. day: 25-28 °C

Temp. night: 20-22 °C

Temp. local: up to 35 °C

Humidity: 70-90 %

Thermostatically controlled floor heating is recommended. Lighting duration must be 12-14 hrs. Daylight fluorescent tubes are ideal. A special UV light is not necessary.

Diet

The diet consists of live insects, such as crickets, house crickets, grasshoppers, cockroaches, zophobas and mealybug larvae, supplemented with some fruit pulp and sweet fruits (e.g. bananas, papaya). Alternatively, special ready-made food for geckos or insectivorous reptiles can be offered. Wax moths should rarely be fed in very small amounts due to their large fat content. Young animals should be offered food daily, adults 4-5 times a week. Regular addition of minerals and vitamins (dusting of feed) is important. Drinking water must always be available, but is preferably taken in drop form from leaves or furnishings

A regular and varied diet promotes health and prevents deficiency symptoms.

Reproduction and breeding

In the male, scale serrations are well defined laterally at the root of the tail (left and right 2 each) and of the same size.

Marble geckos stick their hard-shelled eggs to the decoration. At a temperature of 25-30 °C the incubation period is 100-120 days. Small insects such as fruit flies and micro crickets are suitable as initial food for the young.

Life expectancy can be 10-15 years.

Important

With their lamellar toes (adhesive toes) they can also climb on smooth, vertical surfaces (e.g. glass).

Adult males are very territorial and incompatible with each other. However, they can be well maintained in a group, one male with several females. The sounds of the males sound like a kind of "laughing call".

For the resting phase, for about two months shorten the lighting time by 2-3 hours and lower the temperature by 3-4 °C

With fruit and honey water as food for the feeders, their quality can be upgraded.

The terrarium must have good ventilation without drafts and must meet the species specific needs. Measuring devices such as thermometers, hygrometers, etc. are necessary. The lighting has to correspond to the species-specific day-night rhythm and has to be placed in such a way that the animals cannot injure themselves. The terrarium should be locked in such a way that neither unauthorized persons can open it nor the animals can escape. Contamination must be removed regularly.
