Ready for the latest in spa pampering? Prepare to dunk your tootsies in a tank of water and let tiny carp nibble away. Fish pedicures are creating something of a splash in the D.C. area, where a northern Virginia spa has been offering them for the past four months. John Ho, who runs the Yvonne Hair and Nails salon with his wife, Yvonne Le, said 5,000 people have taken the plunge so far. "This is a good treatment for everyone who likes to have nice feet," Ho said. He said he wanted to come up with something unique while finding a replacement for pedicures that use razors to scrape off dead skin. The razors have fallen out of favor with state regulators because of concerns about whether they're sanitary.
