I just wanted to share some nice footage from Mexico showing a group of clarion agenlfish (Holacanthus clarionensis) cleaning a manta ray that comes within sight of their home reef. It shows that Labroides isn’t the only important cleaner fish, especially when it comes to big pelagics. Clarion angels are listed by IUCN as vulnerable, largely because the majority of the known global population resides at the Revillagigedo Islands near the mouth of the Gulf of California.
