But what happens when they don’t know their area?
I’m guessing they either fight each other or hide in the darkest shadow until nighttime.

Not their area is in my house.

I had fire bellies for a while. When introduced, they hide for a while then... poof! It's like someone flipped a switch! If I introduced a new one into an existing armada, usually the new one was skittish but I kept everybody fat, dumb, and happy so there were no conflicts as much as just silliness (I swear, those things are part amphibian, part Bozo the Clown).

Anyway, just my experience.
