yeah I figured they were just kinda kept in racks there whole lives and didn't come out much. It was weird how they were nice out of the bag but once I introduced them to there new home and let them chill for a few days they got pissed haha. I never got bit by a big one either, just 800 gram male so I'm very jumpy when they try to bite me, its quite hilarious. Its like I know its not going to hurt but it still shocks the hell out of me every time! Hopefully they'll calm down, but I tell you what, it deffinately makes things more interesting lol.
