The bluegill bully (Gobiomorphus hubbsi) is found from sea level to altitudes of 480 metres, and up to 100 kilometres inland. It has distinct blue gill membranes and leopard-like spots on its cheeks. With its upturned mouth it takes mayflies and the larvae of chironomid midges from rocks. Bluegill bullies hide away and are rarely seen in swift-flowing waters.
