Why not? In another thread you said it was a 28qt. In another thread, you said you were using aspen substrate. I also know based on a different thread that you don't have a snake in it yet. How big is your water dish? Where is it? Did you spill water in the tub? Have you put any holes in the tub for ventillation yet?

If your water dish isn't horribly large, and you haven't spilled water in the tub, you probably just need to put some additional ventillation holes in the tub. Also, if your water dish is on the warm side of the tub, try moving it to the cool side.
