🐠 Emperor Damsel (Chrysiptera arnazae)
A Vivid Blue Body With a Bright Yellow Tail and Fin Trim • One of the Least Aggressive Damsels Available • A Natural Flatworm Eater
 
📋 The Emperor Damsel, also known as the Goldtail Damsel, has a vivid blue body with a bright yellow tail, and yellow edging along the dorsal, anal, and pelvic fins, a distinguishing feature from the closely similar Yellowtail Blue Damsel (C. parasema), which lacks the extra yellow fin trim.
It comes from reefs around the Solomon Islands, Papua New Guinea, and eastern Indonesia, formally described only in 2010, having previously been referred to as Chrysiptera cf. parasema due to its close resemblance. Every Emperor Damsel we ship is feeding well.
A notable trait: this is the smallest and least aggressive member of the yellow-tailed damsel complex, and appears monogamous in the wild, a behaviour that carries over into aquarium life. It's fully reef safe and earns its keep by eating nuisance flatworms. Like most damsels, it can become nippy if kept in too small a tank, but in a spacious setup, two or more can be housed together if introduced simultaneously with a size difference, allowing the dominant fish to become male. It reaches up to 6cm, so a 75L tank suits it well.
