Methylene blue is an effective aid to general disease prevention, and may be used for the detoxification of fish suffering from nitrate or cyanide poisoning. Also for use as a prophylaxis against fungus infections of fish spawns. Because methylene blue can be toxic to plants and harmful to biological filtration systems, all treatment should be carried out in a separate hospital tank or other suitable container.
