Cohabitation
A pair or 1.2. Two males will not work together — they fight over territory and the warm spot until one is seriously injured or spends its life in a corner. One male with several females, on the other hand, works reliably. What matters is several warm spots and hides so that subordinate animals can get out of the way, and separate feeding as soon as the animals differ in size.

Notes

Stronger than G. flavigularis, with striking pale lengthwise stripes. It readily takes plant food – a mixed diet matches its natural nutrition.
