Koi Fairy Wrasse - Male

Cirrhilabrus adornatus is a compact fairy wrasse from the eastern Indian Ocean, recorded from Sumatra and the Mentawai Islands of Indonesia, where it lives over rubble along outer reef slopes at roughly 10 to 30 meters. Males show a whitish to pale pink body marked by two large triangular bright-red blotches across the upper forward flank, with a broad red border along the dorsal fin. Females are red to reddish pink, shading to white along the belly, and carry a black spot on the upper caudal peduncle. Aquarium references place the maximum size near 3 inches, making this one of the smaller members of the genus.

Adults are best kept in an established, stable system of at least 50 gallons with generous rockwork that provides crevices and caves alongside open lanes for swimming. A deep sand bed serves no purpose here, since this wrasse retreats into rock at night rather than burying itself, and it may surround itself with a mucus cocoon while resting. A tightly fitted cover is not optional; the species is a capable jumper and will find any gap. Moderate to strong flow is acceptable provided sheltered, lower-flow pockets exist where the fish can rest. Care level is moderate, largely because new arrivals need a mature tank and a careful introduction.

In the wild this wrasse picks zooplankton from the water column above rubble slopes, so captive feeding should emphasize small, meaty items rather than large pieces. Mysis shrimp, enriched brine shrimp, copepods, and finely chopped shrimp, squid, fish flesh, and clam all suit its mouth size. Marine pellets and flakes intended for carnivorous fish can round out the rotation once the fish is settled and feeding confidently.

Feed small portions two to three times daily to match the frequent grazing pattern of a planktivore. Newly introduced individuals are sometimes reluctant to eat for the first several days; fortified live adult brine shrimp often triggers a feeding response and can bridge the gap until prepared foods are accepted. Maintain variety long term to support color and condition.

This is a peaceful, constantly active wrasse that patrols the mid-water and returns to rock for shelter. Expect it to disappear into the aquascape for several days after introduction, which is normal behavior rather than a sign of illness. Providing numerous hiding places reduces acclimation stress and shortens that adjustment period considerably.

Pair it with other peaceful fish and avoid aggressive wrasses that will bully a small, mild-mannered tankmate. Use caution when keeping more than one male of the species; a single male with a group of females is workable only in larger systems. The species is considered reef safe and coral safe, and general invertebrate compatibility is favorable, though very small or juvenile ornamental shrimp may be taken as prey while adult shrimp are usually left alone.

FAQ

Frequently Asked Questions

About the Koi Fairy Wrasse

  • What size aquarium and aquascape does a Koi Fairy Wrasse need?
    House adults in an established aquarium of at least 50 gallons with live rock, numerous crevices, and open swimming room. A secure lid is essential because this wrasse jumps, and a deep sand bed is unnecessary.
  • Is the Koi Fairy Wrasse safe for a reef with ornamental shrimp?
    It is considered reef safe and coral safe, with generally favorable invertebrate compatibility. Very small or juvenile shrimp may be eaten, while adult shrimp are usually left undisturbed.
  • What should it be fed, and how often?
    Offer varied small meaty foods such as mysis, enriched brine shrimp, copepods, and finely chopped marine seafood, with marine pellets or flakes once accepted. Feed two to three small meals daily, and use fortified live adult brine shrimp to start a reluctant new arrival.
