The Goldfish Sanctuary
Skin Flukes (aka Gyrodactylus)
Symptoms: goldfish may scrape against objects to get the flukes off,
fading of colors (fish becomes mucus-covered), skin becomes red in
places, fins may become frayed
These parasites may appear as tiny worms, but are difficult to see.
Gill Flukes are contagious and should be treated immediately.
The first thing to do is to contact your vet or petstore for further
instruction - treatment often involves bathing your fish in a
solution of water and formalin, a corrosive poison, and this is NOT
recommended without expert supervision. It is advisable to move your sick
goldfish to a quarantine tank for treatment.
Prompt action allows for the best recovery.
