Formosan (Adult) Coris 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.

The Formosan Coris is a popular multicolored fish. Females have a bright yellow head with an intense blue stripe behind her eye. Her body is overall dark olive with black polka dots. Males have a brighter body with vertical bands, and a darker face with several blue stripes. Both sexes fins are a brighter orange, and the tail is half scarlet and half white to transparent. Juveniles are an deep tangerine orange with white tiger stripes along its back outlined in thick black and a transparent tail. Young fish are very similar to the Red Coris wrasse but are overall darker. It is also called the Queen coris. It grows to 24 inches and needs an aquarium of at least 300 gallons.
