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.

Wrasses are also able to change their sex during these phase changes.Note: This item may spin a harmless cottony substance in its shipping bag.
