Description
The Knife Flathead (Platycephalus cultellatus) is a predatory marine fish characterized by its flattened head and elongated body, well-suited for ambushing prey on the seafloor. Native to the Indo-West Pacific, it is a formidable carnivore that preys on smaller fish and crustaceans. Due to its large size and predatory nature, it requires a very spacious and specialized saltwater aquarium.
