Once you have the heating and RI under control, then you might want to think of altering your caging just a bit. You want two hides. The one you have is nice, but is way too big. You want something dark and tight, and small enough that you look at it and have to think can it really fit in there? You don't want any extra room. Get two that are exactly the same. Put one on each end of the tank.

The bedding looks fine, and so does the water bowl. Don't worry if things look cramped, they love it.
