Need help w/ a discus disease. Possible parasite? Infection?

[playaslk]

fish is about 5.5 inches. This is a singular white parasite about 1mm in diameter and 1.5mm in its protrusion. It is located about 1 inch below the dorsal fin, and is not present on other fish. This fish does not itch, eats regularly and does not show signs of stress. Any help will be useful.
