Common name: Deepwater wrasse

General information

The Twilight Wrasse, scientifically known as Cirrhilabrus bathyphilus, is a captivating species of wrasse found in the deep waters of the Western Pacific Ocean. This species is part of the diverse and colorful Cirrhilabrus genus, which is well-regarded among aquarists for their vibrant hues and dynamic behavior. The Twilight Wrasse is particularly noted for its deep blue to purple coloration, with males displaying more intense colors and finnage compared to females.

Care

Twilight Wrasses are considered moderate to care for, primarily due to their preference for deeper water conditions in the wild. In captivity, they require a well-established aquarium with plenty of rockwork and hiding spaces to mimic their natural habitat. They are active swimmers and benefit from ample swimming space. A varied diet of meaty foods, such as mysis shrimp and brine shrimp, supplemented with high-quality marine pellets, will help maintain their coloration and health.

Reproduction

Like many wrasses, Cirrhilabrus bathyphilus exhibits protogynous hermaphroditism, where individuals are born female and have the potential to transform into males as they mature or if a dominant male is not present. In the aquarium, breeding is not commonly observed due to the deep-water nature of their habitat and the complexity of mimicking such conditions for successful spawning.

Habitat

The Twilight Wrasse is found at depths typically ranging from 60 to 150 meters, which is deeper than most recreational scuba diving limits. They inhabit coral-rich slopes and drop-offs in the ocean, where they can be seen darting among the crevices. Their distribution includes areas around the Coral Sea and adjacent regions of the Western Pacific.
