Distribution and habitat

The diurnal, arboreal Great Angle-headed Dragons live in the rainforest regions of Malaysia, Thailand and Borneo. As crop followers, they are also frequently found near settlements and cultivated land.

Maintenance

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

1-2 animals

5KRL x 4KRL x 5KRL (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. L 150 x W 100 x H 150 cm is recommended, which should be placed in a quiet and vibration-free place

You need a humid terrarium with strong, vertical and horizontal climbing branches, structured back and side walls (e.g. cork covering), a substrate of forest soil-peat mixture as well as many plants (ficus, ferns, mosses, epiphytes etc.). In addition, a large water section (about 5 cm deep) with clean (moving) water for drinking and bathing. 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: 22-25 °C

Temp. night: 18-20 °C

Temp. local: up to 30 °C

Humidity: min. 80

The lighting duration must be 12-14 hrs. Special lamps with high UV-A and UV-B content are ideal, because daily UV irradiation is essential.

Diet

The food supply consists of live insects, such as crickets, house crickets, grasshoppers, earthworms, centipedes, zophobas larvae. Alternatively, special ready-made food for insectivores can be offered. Wax moths should rarely be fed in very small amounts because of their large fat content. Regular addition of minerals and vitamins (dusting of feed) is important. Young animals should be offered food daily, adults 4-5 times a week. 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

The adult male has a thickened caudal root with a distinct hemipenis pouch.

The female buries her eggs (5-6 pieces) in the substrate, which must accordingly consist of a substrate suitable for burrowing. The incubation period is 70-90 days at a temperature of 18-22 °C. Small insects such as fruit flies and micro crickets are suitable as initial food for the young.

Important

Adult animals behave territorially and there may be incompatibilities among themselves. For the well-being of the animals, moving water (e.g. watercourses, waterfalls) should be absolutely available. Besides sunny places, shady, cooler places are also necessary

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

The terrarium must have good ventilation without drafts and 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
