sweeper

{ Sweepers are small, tropical marine (occasionally brackish) ray-finned fish of the family Pempheridae. Found in the western Atlantic Ocean and Indo-Pacific region, the family contains about 80 species in two genera. One species (Pempheris xanthoptera) is the target of subsistence fisheries in Japan, where the fish is much enjoyed for its taste. Sweepers are occasionally kept in marine aquaria. {
