Blueside wrasse

The blueside wrasse (Cirrhilabrus cyanopleura) is a species of wrasse native to the eastern Indian Ocean and the western Pacific Ocean. It is found on reefs in schools swimming 1 to 2 m above the bottom. It occurs at depths from 2 to 30 m, most often between 5 and 20 m. This species can reach a standard length of 15 cm. It can be found in the aquarium trade.

It feeds on zooplankton. It may be relatively common but declining because of threats: blast fishing, sedimentation, pollution, collection for the aquarium trade and habitat loss of shallow reefs.
