Description
The Bluegill bully is a freshwater fish endemic to New Zealand, characterized by its mottled brown coloration and robust body. Males develop a distinctive blue patch behind the operculum, particularly during breeding. They are territorial carnivores, preferring cool, well-oxygenated streams and feeding on aquatic invertebrates and small fish.
