trust me, im in college, and you dont want to be lugging around a huge tank. get some books do your reserach and fyi
my first tank was a 10. bigger is better, but i realize its not always in the budget or the size range. 20's and 29's are also easily moveable sizes, 30's are pretty long, but if you want length over height you should be able to manage. what kind of tank were you looking to start? FOWLR
, or reef? any ideas on fish?
