Breeding the Rose-Band Fairy Wrasse (Cirrhilabrus roseafascia)

Cirrhilabrus roseafascia is a deep-water fairy wrasse described from New Caledonia. It pairs to spawn pelagically and its planktonic larvae cannot be reared at home; this guide describes its reproductive biology.

Overview

Cirrhilabrus roseafascia (Randall & Lubbock, 1982) was described from Bulari Pass, New Caledonia, in the Western Central Pacific. It is a deep-water species recorded at depths of 30 to 100 m, aggregating over coral reefs or rocky and rubble bottoms, and reaches about 10 cm total length. As a fairy wrasse it is a protogynous planktivore whose reproduction follows the genus pattern.

Sexing

Like all Cirrhilabrus, this species begins life as females, with the dominant individual of a group changing into a functional male. The terminal male grows larger and develops the brighter coloration and longer fins characteristic of mature fairy wrasse males, while females stay smaller and plainer. Recognising the male therefore depends on size and these developed display features rather than fixed sexual traits.

Spawning Behavior & Trigger

FishBase records distinct pairing during breeding for C. roseafascia. Following the genus-wide pattern, a male intensifies its colours and performs a brief 'flashing' display, transiently showing metallic blue or violet patches that are hidden at rest, to advertise spawning readiness and challenge rivals. A receptive female then joins the male in a short paired ascent into open water where eggs and sperm are released; the species' considerable depth places these events well below normal observation range.

Egg & Fry Care

The eggs are small, buoyant and broadcast into open water, hatching into planktonic larvae that drift and feed during a long pelagic phase with no parental care. Rearing such larvae is beyond the means of home aquaria, and this deep-water species is not reported as captive-bred.

Common Challenges

Two factors stack against home breeding: the species naturally lives at considerable depth, and its planktonic larvae require an extended pelagic stage that aquaria cannot reproduce. Keeping adults well demands attention to their deep-reef origin and a zooplankton-based diet delivered in a spacious system.
