The visible symptom is a fine grey-whitish dust similar to velvet on the body or visible spots on the entire body, fins and gills of the fish. In serious cases this dust covers the entire body of the fish and attacks the gills causing breathing problems impeding normal respiration. OODINY FISH is an effective treatment against these parasites eradicating them. This product is formulated for saltwater aquariums and in specific cases it can also be used in freshwater aquariums. If used in saltwater aquariums remove the invertebrates (coral, anemones, star fish) and if in freshwater aquariums remove shrimps and snails.
