I know ich is white spots, but have no idea what these black spots are. They were not there the other day. Does anyone have any idea what these are and should I be worried?
Mine use to get them from time to time. I haven't noticed them in a while. I think it started when she started hosting my frogspawn so maybe the coral was irritating her. I don't think they're anything to worry about though.
They most likely will faid again soon . I've seen my clowns get them from hosting an anemone for the first time while there still getting used to it , so id imagine the same could be true of a hammer or possibly something else.
