Spores attach to the gill surface and germinate to form hyphae. These hyphae proliferate, causing damage to the blood supply and necrosis. Sloughing of this necrotic tissue releases spores into the water, which then continue to develop on the floor of the pond or aquarium if conditions are favorable (i.e. temperatures of 25–32°C (77.0–89.6°F), high levels of organic material, low oxygen levels, and a low pH).

Large areas of necrosis containing fungal spores and hyphae can usually be seen on histopathology with a GMS (Gomori methenamine silver) preparation.

Control is achieved by good hygiene, avoiding the use of raw fish products, and adequate quarantine of all new fish to avoid introduction of the organism.
