A friend of mine has a black and white tegu that we just fell in love with! They are so awesome! So...we went to the Tinley show and couldn't find any black and whites for sale in a decent price range. Long story short my sister ended up with a red tegu. We asked to be sure it wasn't Colombian, he's Argentinian. He was great when we got him, but as soon as my sis got him home and set up, he's a nasty little bugger! I'm guessing that since he didn't have any heat for several days he wasn't as 'lively' as he should have been. He has definitely doubled in size since October, and he's getting a little better, but he still scares me when I go visit my family and try to hold him. He whips you and bites!!!! I read that they can be aggressive as babies/juveniles and that reds are rarely aggressive as adults. Please someone tell me that is true! He's so darn cool!
