This is a pinkish growth that is coming from the back/base of the pectoral fin on the right side of the fish. My water parameters are fine, the filters are very well established. I just noticed this growth today. I didn't see it prior to today. The fish eats very aggressively, but I'm concerned with this being Lymphocystis. I don't want the rest of my fish to get this.
this is the best picture I could get of it
