Weird little fish

The other day my friend, who's working down in Okinawa, told me about some weird little fish. They'd gone to the beach and because the weather was a bit crappy they ended up going to a spa. At the spa they had a bucket filled with little fish. You were supposed to put your feet into the bucket, and the little fish would eat off the dead skin. She said the fish tickled her feet so much she coudn't stop giggling and the other people looked at her as if she was crazy. Hmmmm, I wonder if bizarre, little, skin-eating fish would take off anywhere else in the world?
