hello, i have been fighting off nasty disease for a month now... its affected 28 blood red jewel cichlids and jack dempseys, and oscars and parrot cichlids... i originally believed it was columnaris and had thought it was gone after using kanaplex,fufan 2, maracyn 2.. the spots still have not gone anywhere and my fish still has one cloudy eye and the patch is still there ive also seen there slime coat coming off a little bit too.. im running out of ideas i started them on medicated bacterial and internal parasite food 2 days ago... but im starting to believe its internal parasites but the fish are too big to digest the small little food. heres pictures if anyone can give me any insight... ive also been putting aquarium salt in also
