I'm getting a bearded dragon soon, and other than a turtle about a year ago, I have no reptile experience. I've been reading up on them though, so don't think I'm going into this in ignorance. I am going to be keeping the beardie in an aquarium(not filled with water, of course!), and I have read that there should be a heated side and a cooled side. Will the side my heater is on naturally be a little hotter than the other, or do I need something else? I was thinking about putting reptile carpet on the heated half, and tile on the cool half, because tile is usually pretty cool to the touch, but I'm not sure if that'll do it... Also, can I find a bearded dragon at any old pet store, like, for instance, Petsmart?
