after 24 days in qt and 9 days in copper I found my pintail wrasse at the bottom of the tank, not swimming or moving much. I'm at a loss on how to move on. It had flukes and intestinal parasites that I treated, and the fish has been healthy and eating like a pig, then boom dying at the bottom of the tank. I took him out of the coppersafe treated tank into a bucket and treated with ruby reef rally, but it doesn't look good still. I noticed what looks like it's slime coat sloughing off, but it is dark colored. Not sure how to proceed or if it can be saved
