So I noticed yesterday that my clown fish is acting weird and looks like hell. She will not eat. My other clown fish is out for blood and trying to kill it. My sick clown fish had one smokey eye yesterday, but looks better today. On the black parts of her body looks discolored like faded spots. Tail is all tattered but I think that is from it being attacked. Also heavy breathing. Keeps laying on it’s side or swimming all crazy. Nothing normal. Did water tests and all came back normal. Only have 3 fish in a 30gal tank. Have had the same fish for over 3yrs. Posted pictures. Any help will be great. Looks like she is dying. Please help.
