I saw one at a local mom and pop pet store. It was almost all white with a bit of black speckling. Not 100% sure what kind of Tegu it was. Very cool! They wanted $2,500 for that bad boy though. I'm kicking myself for not getting pics now.
I REALLY want one but even though I have a Burm I decided Tegu requirements for me personally were too much. Last time I checked there was something about giving them at least two feet of dirt for burying or something on top of the enormous cage.
