The Giant Hawkfish (Cirrhitus rivulatus), also known as the Hieroglyphic Hawkfish, can be found among the Eastern Pacific Ocean. They have a golden-beige body with warmer colored streaks outlined by a dark cobalt. Feeding on crustaceans, small fish and even juvenile marine reptiles, their coloration helps them hide from their prey. Reaching a maximum size of 24 inches, they are among the largest Hawkfish known. Given their eventual size, they should be kept in a large tank of at least 180 gallons. Though they do not bother coral, they may not be suitable for a reef aquarium, as they may predate on smaller fish, such as chromis or anthias, or crustaceans. Hawkfish should have caves and outcroppings to hide among, to help them feel safe.
