- Cohabitation
- Keep them singly. Monitors and tegus are territorial; grown animals defend their territory and injure each other with serious bites in the process. Even small size differences mean one animal claims the warm spot and the food for itself while the other falls behind — which is often only noticed once the weaker animal has already lost weight. For breeding, put them together only under supervision.
Notes
A very large, extremely active burrowing monitor – it digs burrows metres long. The space requirement is enormous and is almost always underestimated; a normal terrarium is not enough.
