Another new Taiwan sight

I've seen it on Ugly Betty but never actually in person here in Taiwan but yesterday, we passed a stall that has a big fish pool. Two women were sitting on the side gabbing away pleasantly (and appearingly painlessly) to each other with their feet dangling in the water. Dozens of fish swarming their feet taking little nibbles here and there. Apparently it makes for very soft feet but (shudder) its a new cultural experience I'm not ready for! :-)
