I can't really see the left side of the tank but it looks like the tank is too big, not enough hide boxes and/or they are too big. i don't see a thermometer/hygrometer. the sticky thermometer on the bottom right is not good quality. We need to know the actual temps and humidity but i would definitly move him to a 10 gallon tank, keep his warm side between 88-92 and cool side at 78-82 with a humidity of 50-60 with 2 identical small hides at each end, also get a digital thermometer/hygrometer with probe to make sure your temps are where they need to be. Let him be for atleast a week. hope this helps.
