Fiji Blue Devil Damselfish

The Fiji Blue Devil Damselfish is a brilliantly colored South Pacific endemic that displays an intense electric blue coloration rivaling the more widely available Blue Devil Damsel. What distinguishes this species is its geographic origin from the Fiji and Tonga region, along with a slightly different body shape and temperament that many aquarists find more manageable than its more aggressive relatives. Males often display a striking yellow or orange coloration on the belly and anal fin area, creating an attractive two-toned appearance.

In the wild, Chrysiptera taupou inhabits shallow reef environments in Fiji, Tonga, and Samoa, where it is found among rubble zones, coral heads, and rocky outcrops at relatively shallow depths. Like other Chrysiptera species, it is a small, territorial species that defends a home range centered on a preferred hiding spot. However, compared to the intensely aggressive Chrysiptera cyanea (Blue Devil), the Fiji Blue Devil tends to be somewhat less combative, making it a better candidate for community aquariums.

In the aquarium, the Fiji Blue Devil Damselfish is an outstanding choice for aquarists who desire the stunning blue coloration of a devil damselfish with a slightly more tolerant disposition. At only 3 inches maximum size, it is suitable for aquariums as small as 30 gallons, provided adequate rockwork and hiding spots are available. While it will still defend its territory, the level of aggression is generally manageable when housed with appropriately sized community fish. The species is completely reef-safe, extremely hardy, and eagerly accepts all standard aquarium foods.
