If you just got her you should let her settle in and not handle her for at least 5 to 7 days. BP are nocturnal but even at night they will only come out for a short time, usually just to go from one hide to the other or get a drink. Don't expect to see your BP moving about. If you do that is a sign of stress. Hiding is what they do.
I took the tank temps as ambient. Are they ambient (air) or surface?
