The ambient is almost always 85, it does get a little lower if it gets cold but I always maintain a hotspot of 90-92 so she can warm up if she wants to. Heating setup is 1 150W infared lamp, one 50W infared lamp and a 50-60 gallon Repti-Therm UTH on the right side. I'll move the lamps around as necessary to keep the ambient and the hotspot where they need to be. We did have a cold side hide for her but she completely ignored it and stayed on the branch anyways.
The exposed probe is so that I can measure the hot spot temps with a digital thermometer (I forget the brand) and the ambient is measured with a Fluker's digital thermometer/hygrometer.
I do want to get some plants to put in there so the tank isn't so bare looking, just not sure what kind to use, all the ones that Petsmart sells seem so sparse.
