I'd love to own a Tegu, but I've been looking into Bearded Dragons too. I may be able to get one of those sooner because they don't require as large an environment as a Tegu does; mind you I'm still living in my parents house in a small room.
Before I get a beardie I think I'll put it in a 30 or so gallon tank and while it's living in there I want to build my own viv. This channel makes some fucking cool cages for beardies, or any reptile really, and tell you how to do it too.
Any suggestions for a theme I should use when I decide to make one of those?
