I have a yellow tang that developed 2 white spots on 1 fin. Those spots seem to have about disappeared, but the tang is breathing harder than normal and sometimes rests with its face in front of the outlet of the protien skimmer. Other than that the tang looks, acts, and eats normally. Does anyone have an idea of what is wrong and how do i cure the tang?
all help is much appreciated.
