==Habitat and diet==
Eastern freshwater cod are found in clear-flowing rivers and streams with rocky beds and deep holes within the Clarence River system, to significant altitudes.<ref name=Anon_2004/><ref name=nock_2010/> They inhabit all sizes of rivers and streams. Eastern freshwater cod are [[territory (animal)|territorial]] and aggressive. The bulk of their diet is based on [[crustacean]]s (the large, clawed ''[[Macrobrachium]]'' shrimp and the small, clawless ''[[Paratya]]'' shrimp) and other fish, but they are powerful opportunistic predators and are also known to take insects (e.g. [[cicada]]s), frogs, snakes, lizards, birds, and small mammals.<ref name=butler_2012/>
