Blue Reef Chromis

The Blue Reef Chromis, also known as the Blue Chromis or Humpback Chromis, is a peaceful, hardy, and popular saltwater aquarium fish. It has a bright blue body with a slightly darker hue on the upper back and a black spot at the base of the pectoral fin. The fish has an average size of 3 inches (7.5 cm) and can live up to 5 years in captivity. It is recommended to keep them in groups of 3 or more to reduce aggression.

In the wild, Blue Reef Chromis feed on plankton and small crustaceans. In captivity, they will eat most types of prepared foods such as flakes, pellets, frozen, and live foods. It is recommended to feed them small amounts multiple times a day rather than one large feeding.

It is difficult to determine the sex of Blue Reef Chromis without examining their reproductive organs.

Blue Reef Chromis are known to spawn in the home aquarium, but breeding them is challenging. Spawning can occur in groups, and the eggs are adhesive and will attach to a surface. The eggs will hatch in 2-3 days, and the larvae will be free-swimming after another 5-7 days.

Like many other saltwater fish, Blue Reef Chromis are susceptible to parasitic infections, bacterial infections, and fungal infections. Symptoms of illness include lack of appetite, abnormal swimming behavior, and visible spots or discoloration on the skin. Proper tank maintenance, a healthy diet, and regular observation can help prevent disease.

The Blue Reef Chromis is native to the Indo-Pacific region, specifically from the Maldives to the Society Islands.

Blue Reef Chromis are generally considered safe for most reef aquariums, but caution should be taken with very small shrimp or small fish that may be mistaken as food.

Acclimating Blue Reef Chromis is essential for their well-being. It is recommended to slowly drip acclimate them to the new environment over 1-2 hours.
