The wrasse has been in quarantine for about a week now. It had been eating well. Two days ago I started the copper treatment, using Coppersafe, raising it by 0.5 ppm for the first two days. But yesterday it didn't come out for food at dinner like it used to. So I was concerned and did a big water change and stop copper. Today the copper is 0.19 ppm, I added some carbon to remove the rest for now.
This morning it still didn't look well, lying at the edge of the tank (instead of hiding in the pvc pipe) and it didn't react to food at all. There is a white patch of discoloration on its tummy. I did a quick FW dip but get nothing. What should I do next?
