Hello have a yellow tang in qt. Was recently in a fight with another tang. -he didn't live-. But my yellow tang seems to have a discoloration on the front of it face and mouth area. Hope these pictures below will help. The tang is not eating and and copper level are around 1.96 ppm. Using copper power.
What could this be on the fish face?
Should I stop copper treatment?
Thanks for all your help
