As a mature male, the body coloration is very elaborated. The inferior side of the lateral line is pearly with pinkish reflection. The black or yellow line tend to disappear with age or it can be reduced to a short dash. The superior part is greenish with pink accents until the base of the dorsal fin. The base of the dorsal fin is highlighted by a bright yellow line. Then superimposed over this later yellow line a blue line, a yellow one, green one and finally a fin pinkish one. The iris of the eye is orange.

Distribution & habitat

Biology

The zigzag wrasse can live in small group but is usually solitary and even aggressive towards members of its own species.

Like most wrasse, the chain-lined wrasse is a protogynous hermaphrodite, i.e. individuals start life as females with the capability of turning male later on.

The species is targeted but not thought to be threatened by the aquarium trade. It is listed as Least Concern (LC) on the UICN.
