My opinion, if your room is a constant 74 degrees, no need to have a probe on the cold side of the tank. For your hot side, you can place the probe between the uth and the tub. it may not sit completely level, but it will work. It will work the way you have it just fine, but if there is a big mess of pee or water, it will run out that hole. be prepared for that.

I would get ride of that log hide. It's too big for a snake that size, and it doesn't provide the level of solitude that these snakes like. I would take a look at this thread: http://ball-pythons.net/forums/showt...DIY-hide-boxes You probably have something laying around the house that you can make a better hide for your snake. If you can barely fit your fist in it, it's probably about the right size. I know it sounds petty, but I know that when I finally got the correct size hides for my bp, her whole demeanor changed for the better.
