Description
The Giant Kokopu, often misidentified as a 'Giant Killifish', is a large, robust, and predatory freshwater fish endemic to New Zealand. It features a mottled brown and olive coloration, providing excellent camouflage in its natural stream and wetland habitats. This species requires cool, well-oxygenated water and a spacious environment to thrive.
