A member of the sunfish family, the bluegill is one of the most popular freshwater game fish with anglers because of its tasty flesh and the fact that it puts up a pretty good fight for its size.
Only a limited amount of water is able to be suctioned, so the fish must get within 1.75 centimeters of the prey. In turn, bluegill are prey to many larger species, including largemouth bass, smallmouth bass, trout, muskellunge, turtles, northern pike, yellow perch, walleye, catfish, and even larger bluegill.
