Cohabitation
Keep them singly. Blue-tongued skinks are territorial. Males in particular fight in earnest and injure their heads and limbs in the process; females too claim the warm spot and the food for themselves. For breeding, put them together under supervision and separate them again afterwards.

Notes

Darker and slimmer than the Australian forms, with long black legs. A rainforest species – higher humidity than T. scincoides, but good ventilation against skin problems.
