Well, I left the tang in the sump for 3 days, then as soon as I put him back in the main tank, he went straight after the copperband.
I put him back in the sump/fuge. But I guess he's going to go back to the LFS
(I'll get a fraction of what I paid for him), but what choice do I have?
I dont know if it's just because they are about the same size, or what but its sad as the powder blue a nd the copperband are my two favorite fish..
I also hate to get rid of the powder blue that has done good in my tank for 6+ months, when I don't know if the copperband will live, as I know copper bands are near impossible to keep alive!! But of the two, I do like the copper band alittle more and I'm afraid if I keep the powder blue, it won't matter what new fish I get he will attack them.
