Just cured my fish of what seemed like brooklynella. Now my clownfish has a white spot on his fin that is ripping. My goby has had a ripped tail since I got him. The goby's tail is ripped and has white fuzzy stuff on it. I can't get a picture of the goby but I got one of the clown. Please give me a diagnosis. The spot is on the bottom fin and the second dorsal fin
