Hmm...I have graduated from college about 2 years ago; I got to warn you, unless you are planning a small tank (10g) I would highly recommend not to bring a (29g+); First, the dorm rooms are MINISCULE, not to mention you would most likely share it with a roommate.
Also, not sure about your campus, but I believe they close the dorms on big holidays like thanksgiving, Christmas. Lastly, every 9 months or so, you will have to move the tank as you will move every 2 semester.
I would honestly wait until you move off campus and get your apartment/house (highly recommended, much cheaper too).
