Hello,
I have a 40 gallon breeder qt tank. All 3 heniochus were healthy at first and ate right away. I slowly ramped up coppersafe to 1.8 using the hanna checker and one died a couple of days later. Now my second heniochus is blotchy and top half is faded. It is still eating but definetly rapid breathing. This qt tank is a couple of months old and cycled. I have already properly qt using coppersafe and and 2 doses of general cure on 8 fish which include, hippo, sailfin, flame angel, emperor angel, blue jaw trigger, longnose butterfly, harlequin tusk and a bristletooth tang. My current qt tank has lunar wrasse, chocolate tang, red coris wrasse and the two heniochus. They are all juveiles. 2-3 inch max. Do heniochus not do well in coppersafe?
