Ich, a protozoan parasite, also known as "white spot disease", is caused by the external parasite Ichthyophthirius multifiliis.
This microscopic parasite has a multi-staged life cycle and is invisible during its theront stage. Theronts burrow into gill and skin tissue causing severe electrolyte loss and gill damage and promoting secondary bacterial and/or fungal infections.
Early symptoms of this infection in fish include darting in the aquarium and scratching against the gravel and ornaments.
Fish exhibit labored breathing and may remain at the water’s surface, near filters and aeration devices, and white spots may or may not be visible on fish.
