Apparently this has been around for a while, but this is the first I have heard of it.
Fish Pedicures involve a client submerging their feet in warm water while tiny carp, called Doctor Fish, eat the dead skin. This pedicure method has become very popular in Asian countries and Turkey, and is now making its way to the U.S. Some people say it's the best pedicure they've ever had. The fish are known to soften the feet, eat away dead skin and even calluses. The treatment is supposedly not painful.
