About the Bluegill
Belonging to the sunfish family, Centrarchidae, the Bluegill is one of the most familiar freshwater fish in North America. They boast a deep, laterally compressed body that allows them to manoeuvre easily through dense aquatic vegetation. Although primarily known as an introductory sport fish, their engaging personalities and striking colouration make them fascinating subjects for native-themed aquatic displays.
