I just got my BP yesterday.

Should I try feeding it tomorrow since that is when it is normally fed, or wait till later in the week?
Also last night I turned off the heat light, and this morning when i woke up the tank was at about 80degrees on the hot side, is this to cool? Since i know it should be at about that on the cool side at night.
Should I try to keep the tank at a constant temp? I know some people say have a night time drop, and some say keep it at the same temp all the time.
