🐠 Yellow Wrasse (Halichoeres chrysus)
A Vivid Solid-Yellow Body With a Slender, Elongated Shape • A Constant, Active Swimmer • A Valuable Pest-Control Specialist
 
📋 The Yellow Wrasse, also widely known as the Yellow Coris Wrasse or Canary Wrasse, has a vivid solid-yellow body with a slender, elongated shape. Juveniles and immature females show one or two black spots rimmed in white on the dorsal fin, which fade to a single spot as the fish matures.
It comes from the Central Indo-Pacific, inhabiting sandy reef flats and rubble areas at the reef edge, where it's an active, near-constant swimmer, patrolling the rockwork and substrate throughout the day. Every Yellow Wrasse we ship is feeding well.
This is one of the more valuable pest-control wrasses, actively hunting pyramidellid snails, flatworms, fireworms, and Montipora-eating nudibranchs. It's generally reef safe and won't harm corals or clams, but it can nip at very small ornamental shrimp, especially sexy shrimp, particularly if underfed, so a consistent feeding schedule matters. It's also known to clean parasites off other fish, a behaviour that can look aggressive at first glance but is actually beneficial. This species buries itself in the sand at night or when startled, so a soft, deep sand bed is essential. It reaches up to 12cm, so a 150L tank suits it well.
