Black Margate

The Black Margate is one of the largest members of the grunt family commonly seen in the Caribbean, reaching an impressive 24 inches in length. Anisotremus surinamensis has a deep, compressed body with an overall gray to silvery coloration, a distinctive dark blotch at the base of each pectoral fin, and characteristically thick, fleshy lips. Adults have a somewhat somber appearance compared to the more colorful grunt species, but their large size and dignified bearing make them an imposing presence in a large aquarium.

In the wild, Black Margates are found throughout the Western Atlantic from Florida and the Bahamas through the Caribbean to Brazil, inhabiting coral reefs and rocky areas at depths typically between 20 and 60 feet. They are schooling fish that form dense aggregations during the day, often mixing with other large grunt species such as the White Margate and Blue Striped Grunt. At night, they disperse to feed on crabs, sea urchins, other echinoderms, and various benthic invertebrates. Their strong pharyngeal teeth allow them to crush hard-shelled prey that many other fish cannot consume.

In the aquarium, the Black Margate requires a very large system of at least 250 gallons due to its substantial adult size. It is a moderately challenging species that adapts well to captivity once established, readily accepting a variety of meaty prepared foods. Its peaceful temperament and schooling nature make it compatible with other large, non-aggressive species. This species is reef-safe in terms of not bothering corals, though it will consume ornamental crustaceans and small invertebrates.
