What is a live span of fish?

There's no single answer to "what's the lifespan of a fish" because it varies wildly depending on the species. Here's why:

* Size: Generally, larger fish live longer than smaller fish.

* Species: Some species are naturally long-lived, while others have a much shorter lifespan. For example:

* Goldfish: Can live 10-20 years in the right conditions.

* Guppies: Only live for 1-2 years.

* Koi: Can live for 50-100 years.

* Tuna: Can live for 30-50 years.

* Some sharks: Can live for hundreds of years.

* Environment: Things like water quality, food availability, and predators all impact lifespan.

To find the lifespan of a specific fish species, you'll need to research it online or consult with a fish expert.
