It takes about 150 fish to clean the dead skin from one spa customer.

Each spring women rush to the spa to get pedicures, so those tootsies look pretty and fresh for sandal season. But pedicures don't just involve getting your toenails painted. They also involve removing dead skin and calluses from the bottom of the foot. This skin can be removed through various methods -- via buffing with a pumice stone or through scraping with a metal foot file or razor. Many salons no longer use the metal scraper due to liability issues, but sometimes the pumice stone just isn't enough.

This is where the fish come in. Yep, we said fish. The fish, called garra rufa fish, or sometimes "doctor fish," actually nibble the dead skin from your feet.
