The therapeutic efficacy of potassium permanganate (KMnO 4 ) was evaluated on fathead minnows (Pimephales promelas) infected with Flexibacter columnaris in organically enriched pond water and in organically depleted tap water. Potassium permanganate was bactericidal in tap water but only temporarily reduced F. columnaris in pond water. Efficacy of KMnO 4 in pond water was enhanced by satisfying the demand of organic matter for KMnO 4 . The most effective therapeutic concentration of KMnO 4 for fathead minnows infected with F. columnaris was 4 mg/liter plus the KMnO 4 organic demand.
