Sick blue reef chromis

[apinkmanatee]

Does anyone know what this is? It seems like either loss of color or loss or scales...seemed to appear pretty quickly. Nitrates are 10, ammonia and nitrites 0, salinity 1.025, temp 78. It is on two of them. They are eating and swimming around fine, showing no other symptoms. Pease help! Thanks!

I'm viewing on a phone, so its small and difficult to get a good view. Does it look cottony or slimy or just like the skin was scraped? Could it be aggression? Are they doing anything out of the ordinary (scraping on rocks/sand, rapid breathing, etc)?

It doesn't look cottony or slimy at all. More like the scales are gone. Like maybe it could be aggression. I did watch them with the lights out last night and saw a lot more chasing than I see in the daytime hours. I think that must be it. Anything I can do to stop it?

Oh...also...no, they aren't doing anything else weird, like scraping against rocks or anything.
