Common name: Blue flasher-wrasse

General information

The Blue Flasher Wrasse, scientifically known as Paracheilinus cyaneus, is a vibrant and active fish that adds a splash of color to any reef aquarium. This species is known for its stunning display during courtship, where males exhibit an impressive array of colors and finnage to attract females. The Blue Flasher Wrasse is a small fish, typically reaching about 3 inches in length, making it a suitable addition to smaller reef tanks as well.

Care

Blue Flasher Wrasses are relatively hardy and adaptable, but they do require a well-established aquarium with plenty of live rock for hiding and foraging. They are known to jump, so a tight-fitting lid or screen is essential to prevent escape. These wrasses are carnivorous and thrive on a varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, Blue Flasher Wrasses are protogynous hermaphrodites, meaning they are born female and can change to male if the dominant male is no longer present. In the aquarium, breeding is less common, but with a group consisting of one male and several females, spawning may occur. The male performs an elaborate dance to entice the females to release eggs, which are then fertilized in the water column.

Habitat

Paracheilinus cyaneus is native to the Western Pacific, where it inhabits coral-rich areas of lagoons and seaward reefs. They are typically found at depths ranging from 5 to 40 meters, often swimming in small groups or harems consisting of one male and several females.
