costiasis

costiasis
an infection of the skin, fins and gills of aquarium and hatchery fish by the flagellate protozoan Costia necatrix (or Ichthyobodo; and also Chilodonella, Trichodina). Found in young fish just as they start feeding externally, in colder waters. Stress may be a factor. Fish may show lethargy, appetite loss, flashing, respiratory distress in the form of gill flaring and gasping, fin erosion, and produce abundant mucus, giving a cloudy appearance, hence the other names blue slime disease or skin slime disease. The skin and scales may peel away in strips in acute cases
