Pomacentridae) is a large, colourful damselfish. It earns its name from its brightly striped sides, which are reminiscent of the insignia of a military Sergeant Major. It grows to a length of about 15cm (6 inches).
The fish feed upon the
larvae of invertebrates, zooplankton, smaller fish, crustaceans and various species of algae. They are preyed upon by some members of the Labridaeand Serranidaefamilies. They lay their eggs in patches on a firm substrate and guard them vigorously until they hatch.
Sergeant majors are found throughout the
tropicalreaches of the Atlantic, including off the south coast of the United States, Central America, eastern South Americaand western Africa. They are often found on coral reefs at depths of between 1 and 12 meters.
They are popular
aquariumfish, although their aggressively territorial nature can pose problems if not closely watched.
