I need some opinions on something. I live in a second floor apartment. I'm sure I'm not the only one here obsessed with fish and not living on ground floor. What's the biggest tank you could pull off on the second floor? I got a stand for a 55 gallon, and the stand alone is heavier than a b... but it can also hold 75s and 80gs. Should I dare??? Thats a heck of a lot of weight.
