Cohabitation
As a family group: a fixed pair with its offspring. In the wild the species lives in groups of two to ten, usually two to four animals, that are related to one another and recognise each other by scent; pairs stay together for years. Two adult males do not get along. One male with several females is not this species' natural structure and should only be attempted with plenty of space and visual cover. Unfamiliar adult animals are not readily accepted — new groupings are introduced slowly, with several hiding crevices, several basking spots and separate feeding stations. Juveniles can be raised together without problems.

Notes

Live-bearing and decidedly social – it lives in stable family groups with the young alongside their parents. It needs flat bark and stone crevices as retreats.
