Fungus in Aquarium Fish: Causes, Symptoms, & Treatments

Fungus in aquarium fish manifests as white, cotton-like growths on the fish’s skin, fins, or gills, and is usually an indicator of a compromised immune system or poor tank conditions. These infections are often opportunistic, targeting fish that are already weakened due to stress, injury, or poor nutrition. Although treatable with antifungal medications, prevention is the best approach to managing these infections.
