JAPAN — What should have been an ordinary fish tale took an unlikely turn at an aquarium in central Japan.
Shima Marineland is known mostly for penguins and sunfish.
Seven years ago, a goldfish was supposed to be dinner for the arapaima, one of the largest freshwater fish at the aquarium.
Caretakers threw it into the tank at feeding time, but the goldfish dared to escape from certain death by jumping into a filter pipe.
That led to a narrow basin that cleans water from the main tank. The water there is warm, and scraps of leftover food provided ample nutrition.
The goldfish went undetected for years, and is now 10 inches long and weighs nearly a pound, a giant compared to other feeder fish.
