Recent outbreak resulted in my 3 fish going into qt while Dt runs fallow. Fish treated w copper. Treatment ended 2 weeks ago. Lost a banded goby during copper. everyone else pulled through looking great. Coral beauty stopped eating a few days ago. Tried everything. Different kinds of nori, pellets, flakes, soak in garlic, w added vitamins, without ... no symptoms. Just stopped eating. Parameters tested all within range. Did routine water change yesterday. This morning, CB half dead. Reminding fish (yellowtale damsel, watchman goby) both acting and looking fine. What do I do now? Is it too early for another water change? I’ll be watching the other fish carefully for any issues. Thx
