i was at the pet store today and they had a columbian for sale he looked awesome but he was a mean little guy... the guy at store said some people tried to hold em and they dropped em since he tried to bite and they had to chase em around the store... he also hisses a lot.... my tegu is nothing like that she lets u pick her up whenever and shes calm as can be and hasnt hissed once... what makes the columbians so mean is it because there smaller? theres gota be another reason... reason i ask is cause i like the idea they dont hibernate but it dont matter if i cant handle the little guy lol
