Terrible pic, I know, but all I have at the moment. So, the water in my pond has cleared enough lately for me to see the fish pretty well around the feeder at feeding time. What I just noticed is that about one third of all of the Bluegill seem to have this white fungus looking stuff along their pectoral Dorsal fin. It is nowhere else on their bodies, just along the top. Any idea what this is and why it showed up?
