well, it's sort of I want just one big fish instead of a bunch of litte or medium sized ones. I remember seeing a giant 30" aro in a 300G tank all by himself when I was younger, and I couldn't take my eyes off it. it was just so awesome. no other fish to spoil the mood, just one, huge, dramatic fish.rallysman;577286; said:Why only 1 fish in such a large tank?
