Thanks, everyone! It's all been very much appreciated. I actually ran across that same writing from Rick as well. It's all very interesting. I believe I was checking out TeguTalk, and ran across several pieces on the subject; Evidently it's a very heated topic. At any rate, it's great having a point of origin and/or locality for the blue tegus. Whatever they are, they're awesome! Thanks again for all of the input. I intend on researching more, if possible. I'm going to change out his substrate this weekend as well...
