Scientific name: Chrysiptera cyanea
The Blue Damselfish is a small member of the Pomacentridae family of fish, and is found in lagoons and shallow reefs to 10 meters in depth in the Indo-Pacific Ocean. Blue Damsels feed on algae, copepods and tunicates. Blue Damselfish are a popular, active, and extremely hardy addition to marine tanks.
The Blue Damselfish is a bright blue fish with a black spot on the back end of the dorsal fin. One of the distinguishing features of this fish is that it has a square caudal fin and a pronounced anal fin. It has the ability to turn dark blue and almost black when threatened, a defense mechanism that allows it to hide away in crevices.
They are aggressive and territorial, especially towards other Damselfish. Ideally, Blue Damselfish should be introduced at one time and be the last additions to a tank.
Chrysiptera cyanea requires a tank size of 30 gallons capacity. Blue Damselfish are reef-safe fish and are a colorful addition to any reef aquarium. The fish needs ample hiding places, especially if it is being housed with other Damselfish.
