If you just brought him home I'd resist handling him too much. Snakes of any sort really need a lot of time to just "chill," especially when they've been moved to a new place, otherwise they get stressed out. When I got my boa last year I left him alone for two weeks. No handling, nothing. Then I fed him, let him digest for a few days, and then (and still now) only handle him a few times a week.

I'm obviously not an expert on BP husbandry, but what I've found with my boa is that I don't need to leave the thermometer/hydrogator in his enclosure all the time. Every few weeks I just check up on things. Maybe I've just been lucky, but I've never had any spikes in the temps. He's doing great and super healthy.

Have fun, that's a beautiful snake you have.
