SYMPTOMS

Greyish-white cotton wool like growths around mouth area, snout, edge of scales, on fins and fin edges disintegrate, fungus grows, swelling, slime secretion

An infection will usually first manifest in fish by causing frayed and ragged fins. This is followed by the appearance of ulcerations on the skin, and subsequent epidermal loss, identifiable as white or cloudy fungus-like patches. Gills will change colour, either becoming light or dark brown, and may also manifest necrosis. Fish will breathe rapidly and laboriously as a sign of gill damage.

KNOWN TREATMENT/S

Waterlife: MYXAZIN

Prognosis
Ulcerations develop within 24 to 48 hours. Fatality occurs between 48 to 72 hours if no treatment is pursued.

Oxytetracycline

Sulfate based drug combinations such as TMP Sulfa, Sulfa 4 TMP, or Triple Sulfa, are said to combat the infection. Erythromycin (Maracyn), nitrofurazone, nifurpirinol, acriflavine, chloramphenicol or tetracycline are also suitable treatments. Increased aeration and water agitation will improve dissolved oxygen levels which may assist fish suffering from gill damage.
