Care

Myripristis berndti is a hardy species that adapts well to life in captivity. They require an aquarium with plenty of hiding places and a dimly lit environment to mimic their natural nocturnal habitat. It is important to provide a varied diet consisting of meaty foods such as mysis shrimp, brine shrimp, and small pieces of fish or squid. They are generally peaceful but can be territorial with their own kind, so it's advisable to keep them singly or in a large enough tank to accommodate a group.

Reproduction

In the wild, Blotcheye Soldierfish spawn in groups, releasing eggs and sperm into the water column where fertilization occurs externally. In the home aquarium, breeding is rare, but environmental cues such as changes in lighting and water quality can sometimes induce spawning behavior.

Habitat

The natural habitat of Myripristis berndti includes coral reefs and rocky outcrops in the Indo-Pacific region. They are typically found at depths ranging from 1 to 70 meters, where they hide in crevices during the day and emerge at night to feed. Their geographical distribution spans from the Red Sea and East Africa to the central Pacific, including the Hawaiian Islands and the Tuamotu Archipelago.
