Saw something similar on a discovory channel or PBS show. Some spa in europe or the mideast someplace that had a huge tank/pool of these fish. It is, aparently a really good treatment for certain skin conditions, as the fish eat the dead skin off, without disturbing the underlying healthy skin. Over the course of many treatments, leaves the patient with healthy skin again.

Having never had a pedicure before. (unless having my toenails removed surgically counts) I doubt that I'd spring for this. Although this may be just a guy thing. *shrugs*
