I just bought a few damsel, they seems to be breathing fast, I mean their mouth are opening and closing rapidly, do all damsel act this way? My water paremeter is all ok, the damsels all swimming actively and they ate aggressively as well. BTW
one of my damsel fins ( the two fins they use to swim ) broke into half, I think its because of the small plastic bag when travelling home, they fight with one another. Will the fins recover without placing any medicines?
