Pond Doctor Anti Parasite Treatment is the easiest and most effective way to treat all common fish parasites. Pond parasites are usually diagnosed through unusual fish behaviour; gasping at the surface, flicking against rocks and erratic swimming movements are all sure signs of a parasite infection. Pond fish become sick and can die due to parasites if infected. Anti Parasite can be used to treat white spot, flukes, slime disease, flicking, raised scales, inflamed gills, cloudy eyes and more.
