The Fiji Blue Devil Damselfish Chrysiptera taupou is an absolutely stunning fish. Aquarists are fascinated by its brilliant, gorgeous colors. The bright blue body is accented with small yellow dots and yellowish-orange along the top and bottom. Under the sun the blue reflects neon-like colors of bright greenish-blue.
This species is dichromatic, with distinct color differences between the adult male and female. Both have the same blue body with yellows along the lower portion, but most of the female's dorsal fin is yellowish and becomes translucent towards the rear. The dorsal fin of the male, on the other hand, is always blue on the front part. They will keep their brilliant blue coloring in the aquarium, but it may become darker or deep blue on occasion, depending on conditions. There are a number of descriptive common names they are known by including South Seas Demoiselle, Southseas Devil, South Seas Devil Damselfish, Fiji Damsel, Blue Star Damsel, and Village Belle.
