Okay, quick back story. Spotted ICH a few weeks ago and treated with copper for 14 days at 2.0ppm. On the 15th day, fish were moved into a sterilized 40b and all seemed great for 10 days or so. No sign of illness, everyone is eating well and swimming in cramped but clean and sterile tank until my display tank cycles. I go away for 4 days and come home to this
None of the other fish show signs of it. Am I misdiagnosing? What am I doing wrong?
