This handsome Sun-fish is found in all ponds and streams east of the Alleghanies from Maine to Florida. It reaches a length of eight to ten inches, and is a pan-fish and a game-fish not to be despised. In Virginia and the Carolinas, it is the most abundant of the Sun-fish, and thrives wonderfully in millponds.
