After the first night in QT, the fish developed a discolored whitish light patch on its upper right flank. Swimming, breathing, and eating normally. By the following day, the area quadrupled in size, I performed a FW dip, but the fish was dead by that afternoon. While open sores never developed, the large white border to the area, and the speed at which it spread, leads me to think uronema. Opinions welcome!
