being in college myself and im studying biology as well, I dont have the time to maintain a tank. there is a lot of work that goes into it and you just wont have the time to do it. I go to school full time, work part time, and im lucky if i have an hour to hang with friends. after your freshman year if you think you can handle it give it a try, but i wouldnt even think about it freshman year. By the way i ended up gettting a goldfish because its easyer than saltwater, and i never even really found time to do water changes and ended up getting rid of the tank. Plus your roommates will proabably get drunk and doses your tank with vodka.
