They have paddle-like pectoral fins which allow them to swim quickly. They are always on the move and are great fish for fish-only tanks. They are very active and prefer to be in full view of their owner.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.
