A white bump on a fish's head could be caused by a fungal or bacterial infection. It should be treated by isolating the fish in a separate tank, maintaining good water quality, and using medication specifically designed to treat fungal or bacterial infections in fish. Consulting a veterinarian or a knowledgeable fish expert for proper diagnosis and treatment is recommended.
