RENEE MONTAGNE, HOST:

Good morning. I'm Renee Montagne, with a story that answers the burning question how do you anesthetize a goldfish? Emma Marsh of Brisbane, Australia, noticed her fish Conquer choking on a pebble in his tank. She rushed to the vet, who dripped anesthetic into the fish's water and then pried the pebble out of Conquer's throat. The emergency visit cost nearly $400, which The Independent newspaper calculated made the gold fish ounce for ounce worth its weight in gold. It's MORNING EDITION.
