now that i have had my bp for 4 weeks i am starting to see a few paterns and what she prefers. one is that she doesnt seem to spend much time in areas of the tank that are over 90 F. I keep her cool hide around 82 F and her hot hide varies somewhat. if it is above 90 F she hardly ever is in there, but if it is around 89 she will. i had been keeping her hot hide around 92 - 94 but i dropped it to see what would happen and she has been using it. i do keep a basking area of 92 - 94 F whch is outside the hot hide. maybe its her preference but if it is, i will still offer her temps above 90 F if she chooses to want it.
