Blueside Fairy Wrasse
Cirrhilabrus cyanopleura
Also known as blue-sided fairy wrasse, blueside wrasse, blue-scaled fairy wrasse, yellowflank fairy wrasse, yellow-flanked fairy wrasse, blue fairy wrasse, cyanopleura wrasse, ハナビラベラ, 蓝侧丝隆头鱼, 蓝身丝隆头鱼

A slender reef wrasse in which males show blue to purple flanks, a yellowish area behind the head and long, colourful fins, while females are duller reddish brown. It is popular in reef tanks because it is safe with corals and invertebrates, swims actively in open water and males put on bright flashing displays.

Breeding
It is a protogynous hermaphrodite that spawns in pairs or harems, releasing floating eggs in the water column, often around dusk. Spawning happens in aquariums but rearing the tiny pelagic larvae is very difficult and rarely achieved.
Good to know
It jumps readily, so a tight-fitting lid or mesh cover is essential. Males fight with other male fairy wrasses, and similar species such as C. lyukyuensis are often sold under the same name.
