My pastel male is "jumpy", but I don't think he was handled much. As far as a tub doing anything negative to their behavior, I have to highly disagree. The only thing I could pose to seemingly come near it would be someone putting a bp in a tub and not taking it out very often. That would make a snake jumpy, and maybe a little nippy, but it's not going to come after you like a blood thirsty animal. Bps, and snakes in general, are just not like that.
