I found 4 more dead ones today. When I scooped them out I saw what looks like red sore disease. Looks like some bass have some dorsal fin damage. They may have it too but none dead so far. Not sure how to proceed from here. The recommended treatments (salt or potassium permanganate) may not be practical. Will this likely run its course before loosing all my fish?
I took some pictures and will try to post later.
