These fish must be slowly acclimated over several hours and then allowed to recover peacefully for several hours.The Harlequin is a wonderfully exquisite fish, which is usually only available during the summertime. These fish are white in color with large vertical bands of orange running along their bodies. They have large teeth on the top and bottom that they use to crush crustaceans. They are the ideal fish for a fish-only aquarium because of their beauty and community nature. Keep only one per tank.The Wrasse family of fish is a large group of usually very colorful free swimming fish. These fish are powerful swimmers using their pectoral fins to propel them through the water. Wrasses usually have powerful jaws that enable them to crush their food, which includes worms. These fish usually have long continuous dorsal fins and are found in groups in the wild. The Wrasses are one of the few fish that will bury themselves in the sand when sleeping or during flight. As with most Pomacanthus Angels, these fish go through extraordinary color changes from juvenile to adult. Wrasses are also able to change their sex during these phase changes. Feed crustaceans, shellfish or fish-flesh.Photo by Saltwaterfish.com member, Reefboys.
