Cohabitation
Single housing or 1.1 in a very large enclosure. The reason is territory: two animals will not voluntarily share a basking spot or a hiding place. They fight until one is seriously injured or permanently confined to a corner — and that second animal then eats worse, without showing any visible wound.

Notes

A brilliant yellow monitor that climbs and swims equally well. Very intelligent and active – it needs space, occupation and a large water basin.
