mouth fungus

mouth fungus
a bacterial infection (Flexibacter columnaris or Flavobacterium columnare)(not a fungus) causing a cotton wool-like growth usually in the mouth region. A rapid infection, often fatal, first seen as light grey marks. Usually occurs in aquaria with pH over 6, higher temperatures and hard water and to fish that are already injured. Proprietary treatments are effective and the antibiotic oxytetracycline can be used for valuable fish. Called columnaris disease when found on other parts of the body. Usually occurs in summer in natural waters and is associated with stress, crowding, injury and poor water quality. Virulent forms may show no external symptoms, less virulent forms show grey-white lesions on the body, fins and gills. Lesions first appear on the caudal fin and progress towards the head. Heavy infections appear yellow or orange. Scaleless fish show lesions comprising a dark blue area overlain by a milky veil and with a red-tinged margin. See also saddleback, saddlepatch disease and mouth rot, depending on locality on body
