Ok yesterday we brought home a beautiful Collared Lizard and Sid is having a fit. Running around his viv bobbing his head constantly. He can see the other guys cage at all but they are in the same room. Is this normal and is he going to stop or will I have to separate them. The other guy could care less about Sid but he (Sid) is all up set. I took him out last night and let him run around in a diff part of the house and thats still all he did was run around bobbing his head. Any thoughts on the matter would help.
