Cohabitation

One male with several females, however, works reliably. Several warm spots and hides, plus separate feeding for size differences, matter.

Notes

A compact, live-bearing bush skink. It uses bark crevices and deadwood – the furnishing should offer plenty of flat hides rather than tall climbing structure.
