I started to notice my kole eating less often a few days ago and just noticed today it's starting to look like it's lost some weight. I feed frozen mysis and blood worms as well as nori. Nothing new has been added to the tank; no inverts, fish, coral etc, nothing! My other fish seem fine. The tang isn't rubbing itself on anything. It usually cruises around the tank, but lately it just kinda hangs out in one place. Breathing seems fine; not fast paced or heavy. I have not found any body marks or blemishes, no cloudy eyes or fin rot. Anyone have any ideas? I've had the fish for a few years now.
