Radiant Wrasse (Indian Ocean)

Wrasses are prone to jumping from the aquarium when startled or excited so we recommend a secure lid. They feel most secure when there is plenty of live rock to hide in, as well as open space for swimming. Most species may be kept in pairs or harems as long as they are added together or females first. They do not appreciate living with other species of wrasse, so any aquarium with several species must be large enough and the most peaceful species added first.

They should be fed two to three times a day plenty of high quality meaty items, frozen Mysis shrimp, krill, chopped seafood, marine algae and Spirulina.

Coris wrasses are easy to keep and have active personalities. They have big appetites for invertebrates, especially shrimp; however larger species may attack other crustaceans, snails, worms and starfish among others. They are often employed to eat pests of corals and clams including flatworms, fireworms, Montipora eating nudibranches, and pyramid snails; they may occasionally clean their fish tank mates. They do not bother corals or anemones, but may flip over rocks in their search for food. Large species may also bully or eat small fish, but they are typically nonaggressive with other large fish as long as they have a different shape. Similarly shaped fish are seen as a threat and may be targeted; we do not recommend keeping them with small species such as flasher wrasses.

At night time or when threatened Coris wrasses will dive into the sand for protection. They can even swim under the sand to avoid predators. It is not uncommon to find the wrasse laying on top of the sand to rest during the day. A fine sand bed of at least 2-3 inches will help them feel secure. Rocks should be placed on the aquarium glass and sand poured around them to eliminate the danger of a cave-in when the wrasse dives in.

Once seen, the Radiant wrasse cannot be forgotten! Its colors are more saturated than almost any other fish. A wide stripe along its body is deep maroon and emits an infrared crimson to royal purple all around. Along its back and face is an electric yellow so bright it nearly glows. Two turquoise stripes underlined with magenta run under its eye. Males and females are identical; juveniles have more subtle coloration. The Radiant wrasse is one of the most peaceful of the Halichores species, and also one of the most difficult to keep. It grows to 4.5 inches and needs an aquarium of at least 70 gallons.
