🐠 Red Coris Wrasse (Coris gaimard)
Marine Fish-Only Wrasse • Dramatic Colour-Changing Species • Active Sand-Burrowing Swimmer • Intermediate Marine Fish
 
📋 The Red Coris Wrasse (Coris gaimard), also known as the Clown Wrasse or Yellowtail Coris, is one of the most dramatic transformation fish in the marine hobby — juveniles enter the trade as small, vivid orange-red fish with bold white saddle markings, gradually developing into large, speckled blue-green adults with a bright yellow tail as they mature.
Native to reef environments across the Indo-Pacific, Red Sea, and Hawaiian Islands, Red Coris Wrasses are active, constantly moving fish that hunt through sand and rubble for small invertebrates throughout the day, and bury themselves completely in soft substrate at night or when startled.
Naturally bold and active, this species genuinely earns its popularity through personality and visual transformation, but it comes with two commitments that are important to understand before purchase: adults can reach a substantial 25–35cm+ in captivity, and this species actively hunts and eats snails, hermit crabs, shrimp, and small sea urchins, making it unsuitable for reef tanks with desirable invertebrates. It is best suited to a spacious fish-only or fish-only-with-live-rock aquarium with a deep, soft sand bed.
With adequate space, a deep sand bed, and appropriate tank mates, they thrive as a Bold, Dynamic Fish-Only Display Species.
