Fairy Wrasse Identification Guide

Key identification features

• Small, slender, torpedo-shaped wrasse, generally under 12 cm
• Males show intensely saturated colors — magenta, violet, red, or yellow — often with an iridescent sheen that shifts with viewing angle and intensifies during courtship
• Females are far plainer, pale pink to yellow-orange with little pattern and a more uniform appearance
• Elongated pelvic fins in some species and pointed caudal fin lobes on displaying males
• Lives in loose harems over open reef slopes, with a single dominant male tending several females

Common look-alikes

• Flasher wrasses are similarly colorful but flare and erect their dorsal and pelvic fins dramatically during courtship display, a behavior fairy wrasses do not show
• Anthias are similarly colorful and schooling but have a deeper, more laterally compressed body and a differently shaped, often elongated dorsal fin spine

Where you'll see one

Found on outer reef slopes and drop-offs across the Indo-Pacific, typically in deeper water with current, moving in mixed-sex groups just above the reef.
