Fish pedicure?

BTW, while strolling around the Night Market, we were given an opportunity to have a fish pedicure.  Essentially, you place your feet into a fish tank of tiny fish who then nibble away at your loose skin and what not.  However, none of us wanted to put our feet into a fish tank so we will never know how it feels.  From a friend who did try it, it was akin to numerous little electric shocks.  Hmm, no wonder I passed on this opportunity.
