Hey I have a new to me tomini tang in my QT. In with a carpenters wrasse, Midas blenny. There was a royal gramma but it died yesterday of what appeared to be a parasitic disease. I dosed with copper power to 2.25 over two doses the day I saw symptoms and the day it died. Tank is cycled other two fish are still doing well and tang is eating still. Any help? On the way to petsmart to dose general cute and get some air stones.
