I have a 7" black shark in my 180 gallon. He always hangs out beneath some driftwood but I noticed I hadn't seen him come out to eat in the past couple of days. Yesterday, I checked on him and he had a couple of small light spots on his tail fin. It kind of looked like those parts were transparent. I figured he scraped himself on something. When he still didn't come out of hiding tonite, I found him in his usual spot but now covered in those same spots. They're grayish looking patches covering his whole body and all fins. They're not fuzzy and when he swims under the light, the patches have a gold sheen to them. He still isn't eating and I haven't seen any other fish in the tank bothering him or showing similar symptoms. What is this and how do I treat it?
Tank parameters are fine and I've been performing twice weekly water changes of 50-75%. Within the past month I treated and retreated with levamisole hcl for callamanus worms. After the final treatment, I treated for a week with pimafix to try to prevent secondary bacterial infections.
