lol, never thought of buying a used tank, my brand new 30 gallon was about 500$, then again I got it at bigals so it was probably over priced! Don't most people say that you should have an even number because one might get left out? But then again I am still a teenager so money isnt somethign I have at the moment (looking at a laptop) and I can afford to buy the stuff my for 30 gallon and 60 at the same time. My cousin just bought a 75 gallon, could probably convince her to get discus and owuld just help her and admire her fishies... well see
