The Neon Tetra Disease

Later or sooner every fish keeper will have to face the disease of the tank's inhabitants. Neon tetra disease is a disease that mainly affects the muscles, less often the internal organs of the fish's body. It is caused by parasites of the genus Plistophora. Among aquarium fish, tetras and carp are the most vulnerable, although it occurs in many fish species.
