Cohabitation
In pairs (1.1) or as a harem of 1.2 – males strictly separate. The reason: several males fight over territory and the basking spot until one is injured or permanently sits in a corner. Females usually get along, but each needs her own basking and hiding spot; feed separately if sizes differ.

Notes

An arboreal agama – it needs height and stout horizontal branches under the spot. The male has a brilliant blue head. Markedly shyer than bearded dragons.
