180 for now because i am in a small apartment. next year i am moving into a small house, and i am going to have a much larger tank set up as an "island" or room divider, or whatever you want to call it ... so it will be built into the wall, and visible from 3 sides
it will be in the 400-600 gallon range, although i am not sure yet
if my plans fall through, or fish size becomes an issue, i plan to sell some fish. i dont want them to be trapped in a "tiny" tank. i am sure people will say that my tank is already too small for its stock, but i do water changes on an almost daily basis, and all my fish are healthy and water parameters are always pristine....
