Can fish live for 30 years?
It is not surprising that fish have the longest and shortest lifespans. While a pet Goldfish (Carassius auratus) has a typical lifespan of 6-7 years, they have been reported to live as long as 30 years in captivity. In the wild, the average lifespan for a fish is around 10 years. However, some species can live up to 20 years or more.
This is due to the fact that most fish live in the water for only a few months at a time, so they don’t need to eat as much to maintain their weight. In fact, many species of fish are able to survive on just a single meal a day, which is why they are often referred to as omnivores.

And it’s not just any old fish, either. It’s the largest living fish known to science, with a body length of about 1.5 meters (5 feet) and a girth of up to 1 meter (3 feet), according to the study, which was published online today (May 16) in Science Advances.
What is the oldest fish?
The world’s oldest living aquarium fish is believed to be located at the California Academy of Sciences. According to scientists, the oldest known animal is an australian lungfish named methuselah.
