I have two digital thermometers along with a temp gun, warm side is 88-90, cool side is around 84. The tank is on a UTH hooked up to a thermostat(no built in thermometer for the thermostat). There's a low watt lamp for light, but it doesn't give off much heat, plus it's on the warm side so if it did get warm, it would just shut off the UTH.

The strange thing is she usually hangs out on the warm side, even with identical hides. I feel like if it really was too warm, she'd make her way over to the cool side. Even directly on the glass, it only reaches 93.

I did notice though when I went in to check, that she's pushing up against the lid(a metal mesh top). Not sure what to make of that one or how to get her to stop.
