General information

The Shadowfin Soldierfish, Myripristis adusta, is a nocturnal species known for its striking red color and large, reflective eyes. These adaptations are beneficial for its nighttime activities and for navigating the dimly lit reef environments. The species is relatively hardy and can be a good choice for aquarists looking to add some nocturnal activity to their tanks.

Care

Myripristis adusta requires an aquarium with plenty of hiding places and a subdued lighting scheme to mimic its natural habitat. During the day, they prefer to retreat to caves or overhangs, emerging at night to feed. A varied diet of meaty foods such as shrimp, squid, and prepared frozen foods is essential for their health.

Reproduction

In the wild, Shadowfin Soldierfish spawn in groups, releasing eggs and sperm into the water column where fertilization occurs. In the home aquarium, breeding is rare, but providing a large, peaceful environment with multiple individuals may encourage spawning behavior.

Habitat

This species is found in the Indo-Pacific region, from the Red Sea and East Africa to the Central Pacific. They inhabit coral reefs and rocky outcrops, typically at depths ranging from 3 to 60 meters. They are often found in schools, taking refuge in caves and crevices during the day.
