Common name: Hawaiian chromis

General information

The Oval Chromis, Chromis ovalis, is a small and peaceful member of the damselfish family. It is known for its oval-shaped body and striking coloration, which can range from a pale blue to a deep indigo, often with a lighter belly. This species is not as commonly kept as some other damselfish, but it can make a great addition to a community reef aquarium due to its relatively non-aggressive nature.

Care

Oval Chromis are hardy fish that can adapt to a variety of aquarium conditions. They prefer a well-established tank with plenty of live rock for hiding and grazing. These fish are omnivores and will accept a wide range of foods, including flake, pellet, and frozen preparations. It's important to provide a varied diet to ensure proper nutrition.

Reproduction

In the wild, Oval Chromis form breeding pairs or small groups. They are known to spawn on the undersides of ledges or in crevices, where they lay adhesive eggs. The male typically guards the nest until the eggs hatch. In the aquarium, breeding is possible but not common, and it requires a stable, mature tank with excellent water quality.

Habitat

Oval Chromis are found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They inhabit coral reefs and lagoons, often in groups, and can be found at depths ranging from shallow waters to about 60 feet. They are typically seen swimming in the water column above the reef, where they feed on plankton.
