pistolpete said:I haven't been doing this for long, but while talking with the guy from reptileguru, he said you can sex small tegus by looking for a cluster of odd-shaped scales by the vent, the ones with a cluster are males. I wasn't too sure about this because everywhere I read said they have to be probed, or 20+ inches to sex. This is just something I heard so can anyone give some more insight on that theory.
