I have a 15 year old clown fish that seems to be on its way out possibly. For several weeks she has been sluggish. Today she has been fine but just now I noticed she was on the power head. She seems to have some white splotches on her. Don’t know if that’s from being stuck on the power head. I’ve put her in the sump for now just so she won’t get stuck on a power head. Everyone else seems fine
