The Melanurus Wrasse is very active and helps control pest flatworms in my reef tank. I made sure to provide a deep layer of fine sand and a sealed lid. It’s a great addition to a healthy reef environment.

It’s colorful and energetic. I noticed it eating some small snails, so I adjusted my invertebrate placement. It’s a useful pest controller and stays active throughout the day.
