Adorned wrasse

About

The adorned wrasse (Halichoeres cosmetus) is one of those Indo-Pacific species that rewards closer inspection. The kind of fish you walk past at first, then do a double-take when the light hits it right. Like most members of the Halichoeres genus, it inhabits coral-rich reef environments across the Indo-Pacific, where it spends its days picking through rubble and sand for small invertebrates. This active, always-on-the-move hunting style makes it genuinely entertaining to watch in a well-set-up display tank. As a labrid, it goes through the typical wrasse color phases as it matures, meaning juveniles and adults can look quite different from one another. Something worth keeping in mind when trying to identify one at the shop. The intermediate care rating is well-deserved. This isn't a fish you want to drop into an unstable or newly cycled system, and like other wrasses it needs a tight-fitting lid since they are notorious jumpers. A sandy substrate is a practical consideration too, as wrasses of this group often dive into the sand to sleep or when startled. Given a mature, settled reef setup with appropriate tankmates, it tends to be a rewarding long-term resident.
