Keep in pairs; males kept strictly apart. The reason: several males fight over territory and the warm spot until one is injured or spends its life in a corner. Females usually get on but each needs its own warm spot and hide; feed separately once they differ in size.

Notes

A spectacular threat display with unfolding mouth-corner flaps. A pure wind-blown-sand species: it shimmies sideways into the sand – deep, fine sand is essential. It needs extreme heat by day and a genuine, cold winter rest.
