looks like a virus, can not rem the name. good news is while takes along time it eventually shrugs off, I would still run a course of metroplex or polyguard.

viruses are pretty species dependent, while I can not say for sure this is ussuly the case. if they are all in the same water and it is a virus whole tank already exposed. look at it like fish herpies. cold sores.
seen more common in plecos, my sale fin had one on his lip for almost 2 years before finally shrugging off. never infected any of the other fish. now he is a 12" and nothing to show was ever there. there is no cure.
