Common name: blue chromis

General information

The Blue Chromis, Chromis cyanea, is a small and vibrant member of the damselfish family that is popular among reef aquarium enthusiasts. Known for their striking blue coloration, these fish add a splash of color to any marine aquarium. They are a schooling species in the wild and exhibit a shimmering effect when swimming in groups.

Care

Blue Chromis are relatively hardy and can be a good choice for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of swimming space and stable water conditions. These fish are omnivorous and will accept a variety of foods, including small meaty foods and high-quality flake and pellet foods. It's important to maintain good water quality and provide a varied diet to keep them healthy and retain their bright coloration.

Reproduction

In the wild, Blue Chromis form spawning aggregations where males prepare and defend nests on the substrate. They are open water spawners, releasing their eggs and sperm into the water column. While breeding them in captivity is possible, it requires a dedicated setup to mimic their natural spawning behavior and to rear the delicate larvae.

Habitat

Blue Chromis are native to the tropical western Atlantic, including Florida, the Bahamas, and the Caribbean Sea. They are typically found in coral reef environments, often swimming above stony corals or in the water column near the reef edge. They can be found at depths ranging from shallow waters to about 60 feet.
