What age is the oldest living goldfish?

The oldest documented goldfish lived to be 43 years old. This goldfish, named Tish, lived with a family in England.

However, it's important to note:

* There are many anecdotal stories of goldfish living much longer, sometimes even over 100 years. These stories are often difficult to verify.

* The average lifespan of a goldfish in captivity is around 10 years. This can vary depending on the species, care, and environment.

So, while Tish holds the record, it's always possible that an even older goldfish has existed!
