Yellow / Canary Top Wrasse

Snapshot: Also known as the Yellow Wrasse, Golden Wrasse or Yellow Coris Wrasse. Juveniles rock two fierce black "eyespots" on their dorsal fin, plus a smaller dot by the tail. As they mature, one spot vanishes, leaving a lone warrior mark. And for some alpha males, fine green lines grace their faces.
 
Other tidbits: Can grow up to 12cm or so. Native to the waters of the Indo-Pacific region, the East Indian Ocean, and the Western Pacific Ocean from the Solomons, southern Japan to the Australian coast. The Yellow Wrasse may resemble the aggressive Sunset Wrasse as a juvenile, but don't be mistaken. The Sunset Wrasse is whole different beast! These wrasses are expert pest exterminators.
 
Bare bones must know: Live-rock fish only, fish-only system or reef aquarium with care. Thick, sandy substrate.
