Brian is absolutely right -- diagnosis can be very difficult. My first hunch was a type of fungus, but since you said the fungus med didn't stop or even slow any symptoms, I thought to go ahead and try bacterial/parasite meds. Although if it was a parasite, I would think you'd see signs of it, or the other fish in the tank would start to become ill also. I'm glad you got all the affected fish in QT, and I'm sorry about the other fish that died. I hope this turns around quickly for you!
