There's more than one way to skin a foot. In his beauty salon wedged between a pizza parlor and a taco shop in a strip mall here, John Ho is letting small fish eat dead skin off his customers' feet. "Feels like a bunch of ants running across your feet," said Bill Piatt, a Marine gunnery sergeant from nearby Fort Belvoir, after dipping his feet in a Plexiglas tank for 15 minutes of a fish-assisted pedicure. His wife, Leah, reclining on an adjacent chair, said the nibbling tickled -- "a very odd feeling."
