Goldfish the latest weapon to protect world leaders at summit

In addition to thousands of heavily-armed police and troops, six
goldfish will put their lives on the line to safeguard world leaders
at this week's G-20 summit in the South Korean capital, officials said
Tuesday.

The Convention and Exhibition Center in southern Seoul, which is
hosting the event, will use the fish to check the purity of the water
supply to restrooms.

The center, which shares its water supply with a neighboring shopping
mall and trade center, recycles more than 37 million gallons (142,000
cubic meters) a year at an annual saving of 360 million won (US
$322,436).

Remind me not to check about Korean drinking water in restrooms. I
think I do not want to know much there.
