Blue Reef Chromis

Appearance

The Blue Reef Chromis, or Chromis cyanea, is a stunning, brightly-coloured fish with a deep blue-green body that fades to pale blue-green on the lower portion of the body. They can grow up to 3 inches (7.5 cm) in length.

Natural Habitat

Blue Reef Chromis are found in the western and central Pacific Ocean, from Indonesia to the Great Barrier Reef. They inhabit coral reefs and prefer to stay in the upper to middle levels of the water column.

Keeping Blue Reef Chromis healthy

Care level for Blue Reef Chromis is relatively easy, but they can be a bit on the delicate side. A well-maintained tank with good water quality is necessary for their health. They are sensitive to changes in water parameters, so regular testing and maintenance is crucial. They are also sensitive to certain medications and treatments, so it’s important to research and consult with a veterinarian or expert if any issues arise.

Special requirements and feeding

Blue Reef Chromis are omnivorous and will accept a variety of foods, including flakes, pellets, and frozen or live foods. It’s important to feed them small amounts frequently throughout the day rather than a large meal once a day. They also benefit from the addition of vitamin and mineral supplements to their diet.

How Many Should I Keep?

Blue Reef Chromis are social fish and prefer to be kept in groups of six or more. This not only provides them with a sense of security but also encourages natural behaviours and reduces aggression within the group.

Lighting Preference

Blue Reef Chromis prefer moderate to high lighting conditions that mimic their natural reef environment.

Suitable tank mates

Blue Reef Chromis are generally peaceful and can be kept with other peaceful fish in a reef or fish-only aquarium. Avoid keeping them with large or aggressive fish, as they may become intimidated or bullied. Suitable tank mates include other small schooling fish, clownfish, gobies, and shrimp.

Breeding Blue Reef Chromis

Breeding Blue Reef Chromis in captivity is difficult and rare. The process requires a specific set of conditions, including appropriate tank size, water quality, and diet, as well as a dedicated breeding pair. The eggs hatch into larvae that require specialized care, including proper feeding and water flow, in order to survive.

Sexual Dimorphism

There is no sexual dimorphism in Blue Reef Chromis, making it difficult to distinguish between males and females.

Distribution

Blue Reef Chromis are naturally occurring in the western and central Pacific Ocean, from Indonesia to the Great Barrier Reef. They are also available as captive-bred specimens in the aquarium trade.

Summary

The Blue Reef Chromis is a stunning and relatively easy-to-care-for fish that adds a splash of colour to any reef or fish-only aquarium. While they may be a bit on the delicate side, with proper care and attention, they can thrive in a well-maintained aquarium.
