It will pass....and by the way - it could be both! Puberty seems to be more of a condition where aggression or just strange behavior happens no matter what, where breeding season seems to be aggression toward another female Tegu.Thank you for your reply, I thought puberty was normally 18-24 months old. He went from being a nice tegu to satan. I still sit next to his enclosure and talk to him and attempt to pet him but he gets real defensive. I guess I just have to give him some time and space.
