also tegus go through a "nasty" stage. When they hit their adolencent age and want to mate...are getting their jowls...they can be downright terds!! A tegu that is about 3 feet throwing a tee tee can be a little disconcerting.
I so agree with the poster above...get yourself a beardie...if that goes well....get yourself an iggy....if that goes well then move forward. But make sure you have the room to have a massive cage as that is what they need!!!
