Blackspot sergeant have a zebra stripe look (yellowish-grey with six brown broad bars to brown with 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 in length[4] and are known to live up to nine years in the wild.[2]
Habitat and behavior
    
Blackspot sergeant are common in tidepools and rocky shallow areas (0-3m) with moderate surge.[2][5][6] Juvenile Blackspot sergeant are common in tidepools where they feed on algae, small animals as well as plankton.[6] Once they mature and become bigger, they move towards deeper areas with more surge.[6] Blackspot sergeants are very territorial and often aggressive, in tidepools dominating other fish.[6][3] During the day they are found near rocky areas and at night they are under some type of shelter.[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 especially aggressive.[2]
