Cohabitation
In pairs (1.1) or 1.2; males are incompatible. The reason: several males fight over territory and basking spot until one is injured or sits permanently in a corner. Females usually get along, but each needs her own basking and hiding spots; feed separately if they differ in size.

Notes

The smallest and so the most keepable Hypsilurus species; still tricky to settle in.
