The rock bass (Ambloplites rupestris, Ambloplites constellatus), also known as the rock perch, goggle-eye, or red eye is a species of freshwater fish in the sunfish family (Centrarchidae) of order Perciformes. They are similar in appearance to smallmouth bass but are usually quite a bit smaller. The average rock bass is between 6-10 inches, and they are rarely over a pound. Rock bass are native to the St Lawrence River and Great Lakes system, the upper and middle Mississippi River basin in North America from Québec to Saskatchewan in the north down to Missouri and Arkansas, and throughout the eastern U.S. from New York through Kentucky and Tennessee to the northern portions of Alabama and Georgia and Florida in the south. While fairly good eating cooked fresh, Rock Bass are generally not regarded by most anglers as a food fish of the quality of bluegill or perch. Fishing with live bait such as nightcrawlers is the most effective to catch rock bass, although they are often caught with lures while fishing for bass. A. rupestris, the largest and most common of the Ambloplites species, has reached a maximum recorded length of 43 cm (17 in), and a maximum recorded weight of 1.4 kg (3.0 lb). It can live as long as 10 years. These fish have the ability to rapidly change their color to match their surroundings. It is this chameleon-like trait that allows them to thrive throughout their wide range.
