I just added a copperband butterfly and a cleaner wrasse...and the two striped damsels I have had since I set up my tank have started harrassing them. The wrasse is quick and not really phased by it. However, the copperband is scared enough that he's just hanging out at the top corner of the tank. I'd rather have him than the damsels, but I can't catch them with so much rock in the tank.
A trap may be the best bet, especially if I go a couple days without feeding first.
