Description
editBlackspot sergeants are generally yellowish-grey in colour with six brown broad bars, six to seven narrow light bars and a black spot at the upper base of the tail.[2] They can reach up to 24 cm (9.4 inches) in total length[4] and are known to live up to nine years in the wild.[2]
Habitat and behavior
editBlackspot sergeants are common in tidepools and rocky shallow areas with moderate surge at a depth of 0 to 3 m (0 to 10 ft).[2][5][6] Juvenile blackspot sergeants are common in tidepools where they feed on algae, small animals, and plankton.[6] Once they mature and become bigger, they are known to move towards deeper areas with more surge.[6] Blackspot sergeants are very territorially aggressive, especially towards other fish in tidepools.[6][3] During the day they are often found near rocky areas, although at night they tend to take shelter under various objects.[6] Blackspot sergeants are oviparous and males build a nest site in rocky areas to attract females.[6][2] During this mating period they are believed to be especially aggressive.[2]
