Myripristis amaena, also known as the brick soldierfish or redfin soldierfish, is a species of fish in the family Holocentridae found in the Pacific Ocean. It is reef fish, often inhabiting caves and rock ledges.[2]
Description
Myripristis amaena has a reddish coloring on the upper portion of its dorsal fin and can be distinguished from the closely related Myripristis berndti by the absence of a white leading edge on its median fins.[3] It reaches a maximum size of about 26.5 cm (10.5 in) and has 32–36 lateral-line scales.[4] Individuals reach sexual maturity at approximately 145–160 mm standard length.[5]
Myripristis amaena is a slow-growing species that matures at around 6 years of age.[6] It is considered long-lived for a reef fish, with individuals in Hawaiʻi documented to live at least 14 years,[6] while individuals in American Samoa have been recorded reaching more than 17 years of age.[7] M. amaena grows slowly and lives a long time, which may make it more vulnerable to overfishing compared to shorter-lived reef fish, and it has been suggested that fisheries managers should take this into account.[7] Spawning activity peaks from early April to early May, with a smaller secondary peak occurring in September.[5]
Distribution and habitat
Myripristis amaena is found in the Pacific Ocean. Its range spans from Indonesia and the Philippines, Hawaii and Ducie Island, north to Ryukyu and Minami-Tori-shima, and south to Micronesia.[2] During the day, M. amaena hides in caves or under ledges, generally at depths of less than 30 feet, and comes out at night to feed.[3] It is nocturnal and feeds mostly on meroplankton like crab megalops, hermit crab larvae, and shrimp. It also eats some benthic prey.[5]
