Well I'm here here. I've had fish in the past, you know basic stuff, 10 gallon tanks, tetras, goldfish, that type of stuff. I want to get a little more serious about it now. What is a good tank that will allow me to get some bigger fish? Not just the real small 1" and 2", maybe 3-5"? I'm thinking atleast 20 gallons. I can build a stand, but I'll need to buy the tank itself. What is a typical setup going to cost me that will allow me to have fish that size? Thanks.
