Looking for some help determining what is going on with a new Chromis that I currently have in QT. In the tank are 3 Chromis, 1 Clown, and one Tomini Tang. Currently running 2.5ppm Copper Power and just dosed API General Cure. This is day 3 of QT. I just noticed the discoloration pattern on this Chromis today. It almost looks like he is being picked on by the other fish, and these are wounds from fighting. All the other fish look normal. The 3 Chromis eat voraciously. The Clown eats well. The Tomini tang has not eaten yet but otherwise seems fine hanging out in its PVC pipe. Thoughts?
