DescriptionThis species is common in the western and central Indian Ocean, reaching a maximum recorded size of 18.8 mm from snout tip to tail-fin base. It lives in a variety of habitats, from the lagoons to the open reef drop-offs, in depths ranging from 1-36 m. Subsequent collections record its presence at Rodrigues, Mauritius, the Seychelles and the Comoros off the north-west tip of Madagascar. The scientific and common names are derived from the Greek word meaning “a stream of blood”, referring to the bright red bars under the eye and across the opercle or gill cover. Although not definitely known, this species probably forms “harems”, where a single male establishes a territory in which reside several jealously-guarded females. In fresh and preserved specimens, there is a distinctive dark spot on the upper base of the pectoral fin. This spot is white on live fish.
