Formosa Wrasse (Coris formosa) Care
The Formosa Wrasse, Coris formosa, is best kept in a FOWLR (Fish Only with Live Rock) aquarium of 250 gallons or more. They can reach a length of 24 inches and need large areas to swim in and plenty of rock work as hiding places along with a deep fine sand bed of 4 to 6 inches to sleep in. They are very active fish and need tank-mates that are larger and somewhat aggressive to hold their own against the Formosa Wrasse. Some fish to consider with these guys are angelfish, some semi-aggressive trigger fish, hawkfish and groupers.
We recommend at least 4 to 6 inches of fine sand be both in any QT tank and the final display tank for them to be healthy. They require aquariums with tight fitting covers as they can be easily scared and will attempt to jump out of the tank. When first introduced to a new aquarium they will likely stay buried for a few days.
Only keep one male fish per aquarium and they have been known to bite off stony coral polyps. The aquarium should have small pieces of rocks for the wrasse to ‘play’ with in its search for prey.
These fish are carnivores and will eat most regular fortified aquarium food such as finely chopped frozen or fresh meaty foods. You can feed them brine, mysis, squid, shrimp, clam and flake and pellet foods three times a day.
