Slip your feet into cool water at the fish spa and relax while 150 garra rufa nibble at your toes. This newest health trend uses tiny fish to literally eat the dead cells from your feet and leave your skin soft and rejuvenated. Also known as doctor fish, garra rufa are a type of carp. They actually have no teeth but harmlessly suction your skin clean. Treatment options include hand therapy, foot therapy, and, if you are really brave, whole body therapy with over 800 fish—a sensation that feels like soaking in very bubbly champagne.
