Yup,sunlight is the key to color.I got lucky with that one really blue pic of my boy.I took him out of his basking spot(110 degrees+) and took him outside on a nice 80+ degree January day(gotta love Florida weather

),right after a full shed and there you have it.
I can't wait to see what he's going to look like this summer.He's already twice the lizard I bought in weight and color.
I think the rhinos grow faster too.After seeing all the pics around I almost wish I had gotten a
set of them instead of the ONE I got.Especially seeing how hard it might be to find a suitable mate for him.I know he's gotta be lonely in his cage with nobody to visit..even if I kept them in separate cages they could come out and play frequently.Oh well,guess he'll just have to settle for me..for a while anyway.
