I already have a hatian curly tail lizard. I decided to buy another one last night. When I put the new one in the tank, my other lizard bit on his neck. My first lizard is three times bigger than the one I just bought. Is this nornal? Is he attacking the other lizard or not? The other lizard seems fine. I decided to seperate the two lizard. My question is, is this some sort of meet and greet or is he attacking the other lizard. TIA.
