Richmond's Wrasse

Snapshot: Male Richmond’s Wrasses dazzle in green, blue, and yellow, while females rock a subtle brown with chain-like patterns and hints of orange and yellow near the anal fin.
 
Other tidbits: Can grow up to 19cm or so. Distributed throughout the Indo-Pacific region, around the Indonesiam coast, the Philippines, and some parts of the Great Barrier Reef. It’s a natural pest-buster, munching on fireworms, pyramidellid snails, tubeworms and flatworms. Juvenile Richmond’s Wrasses can change color to blend in, a slick survival trick. It's also part of the cleaning crew, busy removing parasites from other fish!
 
Bare bones must know: Live-rock fish-only system, or reef aquarium with care.
