(Pictured right) Mainly from the Indo-Pacific. The Panther is not known as a picky eater. They should never be kept with smaller fish. They are the most popular of the Saltwater Groupers. They can grow very large, commonly exceeding 12 inches. Panthers have an outgoing personality, often taking food right from your fingertips. The way they swim and the polka-dots make the Panther an amusing and attractive fish.
