About Pseudojuloides cerasinus (Snyder, 1904)
In Pseudojuloides cerasinus, males in the terminal phase have an overall green body and a single blue stripe on the face. They have a distinctive blue mid-lateral stripe located directly above a yellow stripe, and the posterior part of their caudal fin is black with a blue edge. Some males develop black spots on the membranes between the first two spines of the dorsal fin. Females across all species in the genus Pseudojuloides are typically orange or reddish in color. This is a small fish species, reaching a maximum total length of 103 millimeters (4.1 inches). Pseudojuloides cerasinus is currently known only from the marine waters surrounding Hawaii. It is most often found in clear lagoons and near seaward reefs that have coral rubble substrates. Sighting of this species over live coral and algae clumps are rare. It lives at depths ranging from approximately 3 meters to 61 meters (9.8 ft to 200.1 ft), and is more commonly found at depths greater than 21 meters (69 ft).
