Common name: Filamented Flasher Wrasse

General information

The Filamented Flasher Wrasse, scientifically known as Paracheilinus attenuatus, is a small and vibrantly colored marine fish that is popular among reef aquarium enthusiasts. This species is part of the flasher wrasse group, which are known for their dynamic mating displays involving rapid color changes and fin displays. The males are particularly striking with their extended dorsal and anal fin filaments and bright coloration, which can include a combination of red, blue, orange, and yellow hues.

Care

Filamented Flasher Wrasses are relatively peaceful and can be kept with a variety of other reef-safe fish. They require an aquarium with plenty of live rock for hiding and a tightly fitting lid, as they are known jumpers. These wrasses are active swimmers and appreciate ample space to roam. A varied diet of meaty foods such as mysis shrimp, brine shrimp, and finely chopped seafood will help maintain their vibrant colors and overall health.

Reproduction

In the wild, males perform elaborate courtship displays to attract females. In the aquarium, breeding is less common but can occur if conditions are right. A group consisting of one male and several females increases the likelihood of observing these fascinating behaviors.

Habitat

Paracheilinus attenuatus is found in the Western Pacific, from Indonesia to the Solomon Islands, and north to the Ryukyu Islands. They inhabit coral-rich areas of lagoons and outer reef slopes, typically at depths ranging from 5 to 30 meters (16 to 98 feet).
