So I’m on day 15 of the QT protocol and I noticed the one cardinal stopped eating as often as it was. I kept an eye on it and it was kinda hanging out by itself in the back corner. This afternoon it was near the bottom and laboured breathing. Copper was at 2.3 ppm and ammonia was undetectable. I did a 25% W/C and kept the copper level at 2.3 in the new water. An hour later it was still breathing really heavy. I turned up the air pump just to see if that would help. It’s started to list and I knew it wasn’t going to make it. When I removed it, I noticed a linear dark red patch on the one side of the fish. Coincidentally , the side it kept trying to hide. From what I’ve seen and experienced, it is Uronema. The other fish in the QT are not presenting any symptoms and are eating normally. Does this mean I have to change the QT protocol given the presence of Uronema or just finish the 30 days of copper and then Formalin treatment then if no signs in the remaining fish they can go into the DT?
