During a period from about March until June males will not tolerate the presence of other males. They should be separated to avoid protracted fighting.

In the wild, this male combat ritual is undoubtedly an important part of their structured social system. However, in captivity, these fights can become quite vicious and injury can result. Captive individuals don't have the same options for retreat as do free-ranging animals.

Females will also fight before and after oviposition. If females are kept in a group during the breeding season, they should be separated when they become gravid. A nest box with moistened sphagnum moss can be provided for oviposition.
