Rock bass are a species of freshwater fish found primarily in North America. They are known for their distinctive appearance, featuring a dark green to brown body with red or orange eyes. Rock bass typically inhabit rocky areas of lakes and rivers, where they seek shelter and hunt for food, including insects and smaller fish. These fish can grow up to 12 inches long and are popular among anglers for their fighting ability and tasty flesh. Rock bass are often confused with other species, such as largemouth bass and smallmouth bass, but can be identified by their unique coloration and body shape.
