🐠 Fiji Blue Devil Damselfish (Chrysiptera taupou)
A Vivid Blue Body With a Yellow Belly and Side Dots • Endemic to Fiji and Tonga • A Hardy First Fish for New Marine Tanks
 
📋 The Fiji Blue Devil Damselfish, also known as the South Seas Devil or Village Belle, has a vivid blue body with a yellow belly and yellow dots scattered along the sides. Unusually for a damselfish, this species is sexually dimorphic; females show a yellow dorsal fin, while males remain solid blue.
A common point of confusion worth clarifying: this species is closely related to, and was historically classified together with, the more widespread Blue Devil Damsel (Chrysiptera cyanea), and the two share several common names in the trade. The reliable way to tell them apart is the yellow belly and side dots unique to this species, versus the yellow snout-and-tail pattern of C. cyanea.
It comes from the Western Pacific, specifically Fiji and Tonga, inhabiting lagoons and offshore coral reefs at shallow depths of around 1 to 10 metres, where it's often seen in small groups. Under bright light, the blue takes on neon-like greenish reflections, and the fish can darken under certain conditions. Every Fiji Blue Devil Damselfish we ship is feeding well. This is a hardy species and a popular first fish for new marine tanks. It becomes increasingly territorial with age, and is best not paired with more than one of its own kind, though it's a little less aggressive than its close relative C. cyanea. It's fully reef safe and won't harm corals or invertebrates. It reaches up to 8cm, so a 115L tank suits it well.
