Common name: Redtail flasherwrasse

General information

The Redtail Flasher Wrasse, scientifically known as Paracheilinus rubricaudalis, is a captivating and vibrant species popular among marine aquarium enthusiasts. This species is part of the flasher wrasse group, known for their dynamic mating displays, where males exhibit intensified colors and expanded fins. They are relatively small, reaching up to about 3 inches in length, and are prized for their peaceful nature and striking appearance.

Care

Redtail Flasher Wrasses are best kept in aquariums with plenty of live rock and a well-established environment that offers numerous hiding places. They are jumpers, so a tightly fitting lid or screen is essential to prevent escape. These wrasses are not overly aggressive and can be kept with a variety of other peaceful fish. They thrive on a varied diet of meaty foods, such as mysis shrimp, brine shrimp, and finely chopped seafood.

Reproduction

In the wild, males perform elaborate courtship displays to attract females. In the aquarium, successful breeding can be challenging but is possible with optimal water conditions and a stress-free environment. A group consisting of one male and several females increases the likelihood of observing natural behaviors and potential breeding.

Habitat

Paracheilinus rubricaudalis is found in the Western Pacific, particularly around Fiji, Samoa, and Tonga. They inhabit coral-rich areas and slopes, typically at depths ranging from 5 to 40 meters. In their natural habitat, they are often seen darting among stony corals and rubble.

Hobbyists should aim to replicate these conditions as closely as possible to ensure the well-being and longevity of these wrasses in captivity.
