Common name: Angular flasher

General information

The Filamented Flasher Wrasse, scientifically known as Paracheilinus angulatus, is a small and vibrantly colored marine fish that is popular among reef aquarium enthusiasts. This species is known for its dynamic display behaviors, especially during courtship, where males exhibit extended fins and intense coloration to attract females. The common name 'flasher wrasse' is derived from these flamboyant displays.

Care

Filamented Flasher Wrasses are relatively hardy and can be a good choice for both novice and experienced aquarists. They require an established tank with plenty of live rock for hiding and foraging. A tight-fitting lid is essential as these wrasses are known jumpers. They thrive in a peaceful community and can be kept with a variety of tank mates. A varied diet of small meaty foods, such as mysis shrimp and brine shrimp, will help maintain their health and coloration.

Reproduction

In the wild, Filamented Flasher Wrasses form harems consisting of one dominant male and several females. They are protogynous hermaphrodites, meaning females have the ability to turn into males if the dominant male is lost. In the aquarium, breeding can occur if the environment is stable and there are both males and females present. The male will perform an elaborate dance to entice the females to spawn.

Habitat

Paracheilinus angulatus is found in the Western Pacific, from Indonesia to the Solomon Islands, and north to the Ryukyu Islands. They inhabit coral-rich areas of lagoon and seaward reefs, usually at depths where light is abundant but can range from shallow waters to depths beyond typical recreational diving limits.
