Distribution and habitat

The distribution area of the diurnal helmeted chameleons is in the mountainous regions of western Kenya (Grand Rift Valley, Mount Kenya) and Uganda (Mount Elgon) at an altitude of 1,500 to over 3,000 meters. There they live in the bushes and small trees of the high altitude savannahs as well as in shrubs of gardens.


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

One animal 4KRL x 2,5KRL x 4KRL (L x W x H)

Head-torso length (KRL) is measured on the largest animal. For pair keeping, increase the floor space by 20%. A terrarium of e.g. L 80 x W 50 x H 100 cm is recommended, which should be placed in a quiet and vibration-free place.

They need a well ventilated terrarium structured with branched climbing branches as well as robust plants with dense foliage (hiding and shade places), structured back and side walls (e.g. cork covering), a substrate of soil-peat mixture and a small water container or a drip trough. A large portion of the substrate should always be kept slightly moist. At least once a day, preferably in the evening, the inside of the terrarium should be finely sprayed with water (humidity), a rain or mist system is ideal. At night the humidity should be above 90%.

Temp. day: 20-25 °C Temp. night: 10-15 °C Temp. local: up to 30 °C Humidity: 60-80

The lighting duration must be 10-14 hrs. depending on the season. They need high light intensity and daily UV irradiation as well as sunny places with radiant heat.


The food supply consists of live insects, such as crickets, smaller grasshoppers, cockroaches and crickets. Sometimes the switch to commercial ready-made food for insectivorous reptiles, which must be offered with tweezers, is successful. Wax moths should be fed infrequently and in very small amounts because of their large fat content. Regular addition of minerals and vitamins (dusting the food) is important. Since water is almost only absorbed in drop form from leaves or furnishings, a dropper is recommended, alternatively they can be watered daily from a pipette

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

Reproduction and breeding

The larger male has a thicker tail root with a clearly visible hemipenis pouch. The female incubates her eggs (up to 22 eggs) in the abdominal cavity (ovoviviparous). After 150-200 days of gestation, she randomly sticks the young, which are surrounded by a sticky cover, into the branches. Fruit flies and micro crickets are suitable as initial food

The life expectancy can be 4-6 years.

Species protection

The animal population must be reported to the competent authority in writing immediately after the start of keeping. Your pet store will be happy to provide you with further information.

Protection of species: WA Appendix II; EU Appendix B. The proof of purchase is the required proof of origin for the animal. Please keep it safe!


They are hardly aggressive within the species and can also be kept in a group. It is important to lower the temperature by at least 10 °C at night.

Outdoor keeping in summer, in an aviary suitable for the species, is beneficial for the well-being of the animals due to the temperatures prevailing in Central Europe. For the resting phase, the lighting duration is reduced by 2-3 hours for approx. two months and the daytime temperature is lowered by 6-10 °C as well as the air humidity is reduced.

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
