Tish, the oldest goldfish in recorded history, lived to the ripe old age of 43. In his later years, his scales actually started changing from gold to silver.
The average lifespan of a common goldfish (Carassius auratus), is 10-15 years, but the current Guinness Record for the oldest goldfish ever was set by a male goldfish named Tish that remarkably reached the age of 43. He spent his life in a fish bowl in North Yorkshire, UK, under the care of Hilda Hand and her son Peter. The latter won Tish as a prize at a fairground roll-a-penny stall in 1956, when he was only 7 years old, and after he left the family home, his mother continued looking after the aging goldfish. No one really expected Tish to reach his 40s, considering that most goldfish barely make it past a decade, but somehow he did, and, 24 years after his death, he still holds the record for the oldest goldfish ever.
