Okay I've had th fish in my salt water tank for almost four years and now it is starting to change color. It used to be a gorgeous silver fish with a yellow tail. He is now covered with what seems to be a thin dark grey layer of scum. His overall body functions have slowed down as well. He used to jump up to get his food and swim with such exhilaration. Now he just stays in the same place. Please help!!
