Here is a little information on the Choati Wrasse (courtesy of Blue Zoo Aquatics).
The red spotted coloration on the Choati Leopard wrasse is a striking addition to a reef or fish only community aquarium. The Choati Leopard Wrasse has similar dietary requirements as Mandarin Dragonettes and will spend it’s day searching for copepods and other tiny, almost microscopic crustaceans. These tiny crustaceans are found in well established aquariums and in order to keep the Choati wrasse healthy, numbers of these tiny creatures must be maintained. It is recommended to have either a sump or refugium to give a safe place for copepods and other small crustaceans to multiply safely without predation.
