We saw plenty of these chaps. The Sergeant Major or píntano (Abudefduf saxatilis, family 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 six 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 Labridae and Serranidae families. The female lays her eggs in patches on firm substrate and then gets chased away by her suitor. The boys then guard the eggs vigorously until they hatch. Sergeant majors are found throughout the tropical reaches of the Atlantic, including off the south coast of the United States, Central America, eastern South America, including the island Bonaire and western Africa. They are often found on coral reefs at depths of between one and twelve meters.They are popular aquarium fish, although their aggressively territorial nature can pose problems if not closely watched.
