A mimic/chocolate:sad:, i just lost mine(avatar).Had him 2+ years,its awsome to watch them change.Anyway,if it gets too crazy in there,try the mirror trick.Place a small shaving mirror or something 5X5 inches ,the pbt will be way more interested in the fact that there is another one of him in there,he won't really bother the new guy.Then you can remove the mirror in a few days.The pbt will always be aware of the fact there was another one in there, and kinda be looking over his shoulder, in a way,and SHOULD leave your new one alone.Good luck.Look forward to a pic also..
