Treat Ich (White Spot Disease): Causes, Symptoms, & Treatments

Ich, or White Spot Disease, is a common but potentially serious condition affecting aquarium fish. Caused by the parasitic protozoan Ichthyophthirius multifiliis, this disease is characterized by the appearance of small, white, salt-like spots on the skin, fins, or gills of the fish. These symptoms often coincide with behavioral changes such as scratching against objects, loss of appetite, or lethargy. Although Ich is introduced into aquariums through new, unquarantined fish, plants, or decor, it thrives in tanks with poor water quality and stressed fish. Treatment typically involves using a disease-specific medication and adjusting environmental conditions.
