Two goldfish have become the smallest and hardiest survivors of the devastating February earthquake in Christchurch that killed 181 people. The fish, named Shaggy and Daphne after characters from the animated television show Scooby Doo, spent four and a half months - 134 days - trapped in their tank in the citys off-limits downtown without anyone to feed them or even any electricity to power their tank filter before they were discovered this month and rescued. Luckily for the fish, they lived in a large 26-gallon tank and may have gleaned some nutrition from eating algae growing on the tanks rocks and walls. Its certainly an incredible story. I wouldnt have guessed that fish could survive on their own for four months, said Paul Clarkson, curator at the Monterey Bay Aquarium in California. Goldfish are very hardy critters. He said naturally growing bacteria may have helped keep the water clean enough to sustain life. TG
