Care

Chromis okamurai is a hardy species that can adapt to a variety of aquarium conditions. They thrive in well-established tanks with stable water quality and plenty of swimming space. A group of these fish can create a dynamic display as they are active swimmers and exhibit schooling behavior. They are omnivorous and will accept a wide range of foods including small pellets, flake foods, and frozen or live brine shrimp and mysis.

Reproduction

Like many damselfish, Chromis okamurai are known to reproduce in captivity, though breeding them can be a challenge. They are egg-layers, and males typically prepare a flat surface where the female can deposit her eggs. The male then guards and tends to the eggs until they hatch.

Habitat

Chromis okamurai is native to the Western Pacific, particularly around Japan and Taiwan. They are typically found in shallow, coastal reefs and lagoons, often associating with stony corals and other reef structures that provide shelter and feeding opportunities.
