These invasive fish are challenging targets outside of spawning periods when fishing should be avoided to prevent disrupting reproduction.

Distinguished by their blue-gray coloration with white bellies, broken lateral lines, and distinctive breeding colors - males develop metallic blue heads with vermillion dorsal fin edges and pink caudal margins.

Adults typically reach 16-20 inches and 2-4 pounds, though specimens up to 21 inches have been recorded.
