in a few i know of around here, USA, you can have anything that lives in a small cage or small tank. but to be safe, since most dorms have more than one person to a room and you cant chose who you room with a lot of times, i wouldnt want them coming in with buddies while i was out to class and messing with it and hurting it. i would try to live off campus. safer in my oppinion for the animal. and less stress on you.
