Would it be a bad idea to have 2 tegus in a cage that is 8'x4'x3'? Is that not enough room to avoid fighting? Also, for those who free roam, if you have 2 males out at the same time will they start to fight? I had this problem with 2 male rhinos and I had to let them out at separate times. The tegus I have seen in videos just getting along, but I want to be sure before getting another one. Thanks for the help.
