Summary:
A small orange to orange-brown flasher wrasse with purplish-blue to bright neon blue body stripes. Males have a sharply bicolored anal fin that is yellow basally and reddish-orange distally, a yellow spinous dorsal fin, a single red dorsal-fin filament comprising three segmented rays bound by membrane, and a rounded caudal fin with two concentric blue bands.
In Australia, this species was previously misidentified as Paracheilinus rubricaudalis, which occurs in Fiji, Vanuatu and eastern Papua New Guinea.

Biology |
A protogynous hermaphrodite - all individuals start life as females, and the dominant female may change sex into a male during her life cycle. This transformation from female to male may take a couple of weeks. Flasherwrasses are broadcast spawners, releasing eggs and sperm into the water column. |
|
Etymology |
The species is named in honour of Amanda Hay, Ichthyology Collection Manager at the Australian Museum, Sydney. |
