Gray Angelfish pair

Fish. Mostly solitary and territorial, gray angelfish are sometimes found working in pairs. At full growth, they are 25-60 cm (10-24 in) long and may weigh nearly 2 kg (4.5 lb). They live in coral reef environments, in depths of 2-30 meters (6-99 feet). They are larger than average and somewhat aggressive compared to other saltwater fish. Youngsters occasionally clean parasites off larger fish. Young gray angelfish look quite different from their adult versions, starting out black with yellow stripes and changing color dramatically as they grow. These fish make a sound like a moan in recognition of each other.
