Care

Bluelined monocle breams are moderately easy to care for, making them suitable for intermediate aquarists. They require a spacious tank with plenty of swimming space and rockwork or decorations to provide hiding spots. These fish are omnivores and will accept a variety of foods, including frozen and dried preparations, but should be offered a balanced diet to maintain their health and coloration.

Reproduction

In the wild, Scolopsis xenochroa exhibits a group-spawning behavior where several individuals release eggs and sperm simultaneously. In the home aquarium, breeding is not commonly reported, and the specific reproductive behaviors in captivity are not well-documented.

Habitat

The Bluelined monocle bream is found in the Indo-Pacific region, inhabiting coral reefs and lagoons. They are typically seen at depths ranging from shallow waters to about 25 meters. Their natural distribution includes areas from the Red Sea and East Africa to the Western Pacific.
