Need A Little Help!

[fishmonkey]

depending on your budget, you can make a tank as large as you want, but it is true that bigger is better.

and are you sure that you want to do a reef tank? or do you just want to do a Fish Only With Live Rock or do you want to do a Fish Only tank. A reef tank is a lot more expensive than a FOWLR or FO tank. you need good lighting and other things that can get the price up there. not saying that you cant do a reef tank, its just more expensive and needs a little more mantenance...
