I have some experience with snakes, geckoes, water dragons, iguanas, bearded dragons etc. I even had some monitors... but those are my first Tegues and I'd like to know as much as I can for my new reptiles... I don't even know which type are they... B/W Tegu? Black Tegu? Argentina/Brazil Etc.... I'll try to send some pic's of them and we'll see if you guys can help me. btw, can I know their sex by this size?
