It looks like he is trying to get out!
The HOTTEST SPOT on the bottom of the enclosure on one side should be maximum 92 F.
The ambient temps should be in the low 80s. The COOLEST area in the tank should be maximum 82 F, minimum 78 F. in that range.
I have mine set this way. The hot spot is heated by heat tape under the enclosure and is set to 92 F. The ambient temperatures are regulated by the room temps, typically the coolest part of the enclosure is around 81 F in my enclosures.
They need a way to cool off sometimes, and a temp around 80 F will allow them to do so.
