Its a shame you are dropping out for while, the scape in that tank was very impressive for a young fairly inexperienced guy.
Still you have to do what you have to do, i would suggest a small basic tank as others have, just a 20G with some guppies and cories will only take 30mins a week to look after and keep you on the scene.
During my late teens and early 20s i found having a tank was a calming influence in all the excess and chaos. I enjoyed having a tank as it was a small part of my life that was just for me, didnt involve work, idiot friends or girls. It was always cool to do a WC and spend an afternoon by myself driving around cruising the LFS , listen to some music and chill. Might be worth considering as a break from what looks like a fairly busy schedule.
Thank you for the kind words! I do hope to get back into the hobby with a tank around that size. When I return to the hobby, I don't want to go bigger immediately; I want to start reasonably and work my way up to a proper Monster Fish Keeper's tank. (Plus, it might be the only thing I can afford once I move out of my parents' house, lol.)
