Sunfish are small, typically less than 12 inches in length, and have laterally compressed, rounded bodies with vibrant colors. They inhabit ponds, lakes, and slow-moving streams, feeding on insects, crustaceans, and smaller fish. Sunfish are popular among recreational anglers, especially children, due to their abundance and willingness to bite.Click here to read more about Sunfish.
