I was on craigslist.come the other day.. and there was a guy who claimed to be a reptile rescuer... he had pictures posted of he reps.. but he had a Tegu mixed with a Nile monitor!!!! In the pic the Nile monitor was standing on top of the tegu all puffed up (neck was puffed out) I just thought it was horrible and i feel the need to vent..cause your not sopose to mix speicies like that (and the tank was so small)..He tried telling me that he tried sperating them and they wouldnt eat! I dont believe that for a secound!
