Key identification features
- Small, slender, torpedo-shaped wrasse rarely exceeding 20 cm
- Males show a bold zigzag stripe combining orange and electric blue running along the flank
- Females and juveniles are far plainer: pale brown to olive above with a single dark horizontal stripe and white belly
- Pointed snout and continuous dorsal fin typical of Coris-type wrasses
- Constant, undulating swimming motion close to the substrate
- Sexually dimorphic coloring is strong enough that males and females are often mistaken for different species
Common look-alikes
- Corkwing wrasse: has a distinct dark eye-spot on the tail base that Rainbow Wrasse never shows, and a deeper body shape
- Ballan wrasse: much larger and heavier bodied, lacking the fine zigzag stripe pattern of male Rainbow Wrasse
- Female-to-female confusion with corkwing or goldsinny wrasse: plain brown females can be confused with other small wrasses, but Rainbow Wrasse females lack any tail-base spot and have a more slender profile
Where you'll see one
Rainbow Wrasse are abundant over rocky reefs, seagrass meadows, and sandy patches throughout the Mediterranean and adjacent eastern Atlantic coasts, typically in shallow water down to about 20 m, often seen in loose schools.
