Species group: Chromis
Other common names: Blue Reef Fish; Blue Reef Chromis; Reef Damsel
Scientific name: Chromis cyanea
Blue Chromis are omnivorous, enjoying finely chopped fish, shrimp, mussels, shellfish, as well as flakes and green food. A varied and nutritious diet helps maintain their bright blue coloring.
The Blue Chromis is bright electric blue with black streaks and freckles all over including the fins. A black outline edges the bottom of the dorsal fin and around the deeply forked caudal fin.
It is a relatively small shoaling fish that constantly swims in the open. The Blue Chromis is a popular beginner fish because it’s hardy, peaceful, and easy to care for. They prefer to be kept with their own kind, actively schooling in groups of 6 or more. They will thrive in a reef aquarium with no aggressive tankmates that could eat them.
A reef-type aquarium of at least 30 gallons would be ideal for the Blue Chromis. It is a schooling fish, therefore, requires lots of swimming space and well-aerated water. They are active swimmers that add interest to the top level of the tank.
