Myripristis adusta

Datasheet

General Description

The Shadowfin soldierfish, scientifically known as Myripristis adusta, belongs to the Holocentridae family. Typically displaying hues of red and grey, this species is mainly active during low-light conditions and can often be found hiding among rocks and caves within the aquarium.

Aquarium Suitability

Considered suitable for aquariums, this fish requires careful attention when housed with smaller fish and crustaceans due to its predatory nature. It can coexist with its kind but might exhibit aggression towards similar species if not provided with sufficient space to establish territories.

Demands

The Shadowfin soldierfish can thrive in a reef setting but must be monitored cautiously due to its potential threat to small crustaceans such as shrimp. They are nocturnal creatures, becoming more active in dimly lit environments and will benefit from overhangs and caves within the tank.

Care and Hardiness

Regarded as hardy, this species can endure varying water conditions within the parameters of a pH level ranging from 8.1 to 8.4, a specific gravity between 1.020 and 1.025, and a temperature of 22.2 to 25.6 degrees Celsius. To acclimatize them effectively, it is suggested to begin with dim lighting and gradually increase brightness.

Reef Suitability

While deemed reef safe with caution, the Shadowfin soldierfish may pose a risk to smaller invertebrates and thus should be introduced into a reef tank with care and consideration for potential prey species.

Aquarium Setup

Creating an environment with ample hiding spaces, such as overhangs and caves, is essential for accommodating the Shadowfin soldierfish. Providing dim lighting initially, and gradually accustoming them to brighter conditions, can enhance their adjustment to the aquarium.

Behaviour

With a mostly peaceful temperament, this species may exhibit aggression towards similar species, necessitating adequate space to reduce confrontations. Shadowfin soldierfish are known to be secretive, preferring to hide among rock structures and appearing less active in open water.

Feeding and Diet

In captivity, these fish can be fed a diet consisting of fish, larger crustaceans like shrimp and crabs, other invertebrates, and small crustaceans such as krill and mysis. Luring them with live food initially may encourage feeding, especially if they are hesitant to consume during daylight hours.

Dimorphism

Information regarding dimorphism and captive reproduction of the Shadowfin soldierfish is currently unavailable.

Habitat and Distribution

The Shadowfin soldierfish is native to the Indo-Pacific region, ranging from East Africa to the Ryukyu Islands, including destinations like the Line, Society, and Tuamoto Islands, and extending south to the Great Barrier Reef. Notably absent in the Red Sea, Gulf of Aden, Oman, and the Persian Gulf, this species inhabits a diverse range of marine environments.
