Shadowfin Soldierfish – Facts and Photographs

The Shadowfin Soldierfish (Myripristis adusta) is also known as the Blackfin Soldierfish, Blue Squirrelfish, Bronze Soldierfish and One-spot Squirrelfish.

Soldierfish are in the family Holocentridae and sub family Myripristis and are closely related to the squirrelfish in the sub family Holocentrinae. They differ from Squirrelfish in that they do not have sharp spines on the gill cover and it is unclear how they obtain the common name of One-spot Squirrelfish. They are one of the least common Soldierfish on the Tanzanian coast and are not often seen on the mainland coast. They are more common on Mafia Island and Zanzibar.

APPEARANCE

Shadowfin Soldierfish  have a silver body with dark red edging on their large scales.  The dorsal, anal and caudal fins are edged in black with a thin red purple line close to the black. Being nocturnal feeders they have proportionally large eyes. They grow up to 35 centimeters in length.

SHADOWFIN SOLDIERFISH IN THE WILD

Shadowfin Soldierfish are usually seen during the day  under ledges and in caves. They are generally shy and will head into the corals if a diver gets too close. They are often found in quite large groups around the branching corals with other species of Soldierfish and Squirrelfish. During the night they are seen solitary.

HABITAT

The Shadowfin Soldierfish is found across the Indian ocean and into the west Pacific, excluding the Red Sea and Persian Gulf areas. They are found from depths of 10 to 30 meters usually in deep lagoons and outer reefs.

COMMERCIAL EXPLOITATION

Shadowfin Soldierfish are not exploited commercially but they are sometimes caught by subsistence fishermen and the flesh is white and reportedly very tasty.

AQUARIUMS

Shadowfin Soldierfish grow quite large and unless you have a large aquarium of several hundred gallons, you should not keep them. They require an overhang or cave to hide in. If space is at a premium they may become territorial and bully smaller fish who enter their daytime hiding spot. They are easy to feed and care for.
