  • Prevents fungal infections on fish eggs
  • Treats nitrite and cyanide poisoning in fish
  • Treats fungus and external protozoan parasites on fish

Methylene blue is commonly used by fish breeders to prevent and treat fungal infections on fish eggs, as well as treat fish with cyanide and nitrite poisoning. As a secondary use case, it can help treat superficial fungus and some external protozoan parasites on fish. The disease symptoms can include white tufts or strands on the body (fungus) and scratching on the tank bottom or objects (external parasites).
