Damselfishes are lively and quick, and are usually strongly territorial and aggressive. Most damselfishes live along reefs, but certain species, the anemone fishes, are noted for living among the stinging tentacles of sea anemones. Better-known members of the family include the bright-coloured species of Pomacentrus, the black-and-white, or three-stripe, damselfish ( Dascyllus aruanus ) of the Indo-Pacific; the garibaldi ( Hypsypops rubicunda ), a bright orange California fish about 30 cm long; the beau gregory ( Eupomacentrus leucostictus ), a blue-and-yellow Atlantic species; and the sergeant major ( Abudefduf saxatilis ), a black-banded, bluish and yellow fish of the tropics.
