Hi, I have a pretty good sized tank and I've been wanting a copperband for a while. I was thinking of getting two at the same time, hoping that one would start to eat and drag the other with them once they see the pattern. I did this with mandarins, I had two tanks, one with a mandarin that wouldn't eat and one that did eat. I put them in the same tank and the second starting eating. Would this work with copperbands, or would they fight? I have a 240, +180 sump so think I should have enough water volume and 90 gallons of the sump is a fuge.
