So i have a normal male BP, he's housed in a 20L glass tank currently. Here is some background for the setup:
Cool side temp 80-82
Warm side temp 92-94
Ambient 80-82
Humidity 50%

The tank has 2 identical hides(one warm side, and one cool side) which fit him tightly, temp is controlled via an UTH attached to a thermostat.
No lights are setup for the tank, however the room gets lots of ambient light from a window.

So now for the question...He spends all of his time on the cool side of the tank (now granted im not sitting here looking at him all the time, but i never see him in the warm side hide. It would lead me to believe that the warm side is too warm....but considering that i've check the temps with two different thermometers i know this isnt the case.... So i guess im asking, is it normal for him to spend ALL his time on the cool side of the tank?

Could the fact that i use the room he's in frequently in the evening (i.e. light in the room is on for a few hours a night) have anything to do with this behavior?

I've had this BP for a little over a month, i feed him every friday, and he feeds like a champion. He's yet to defecate(which is also a little bit of a concern), or shed. Any insight would be appreciated!
