How many years those a catfish live?

The lifespan of a catfish can vary greatly depending on the species. Here's a general idea:

* Smaller catfish: These typically live for 5-10 years.

* Medium-sized catfish: These can live for 10-20 years.

* Larger catfish: Some species, like the blue catfish, can live for 30 years or more in the wild.

Factors affecting lifespan:

* Species: Different catfish species have different lifespans.

* Environment: Factors like water quality, food availability, and predators can affect how long a catfish lives.

* Aquarium conditions: Catfish kept in aquariums tend to have shorter lifespans than those in the wild due to factors like limited space and diet.

For example:

* Channel catfish: Can live for 15-20 years.

* Blue catfish: Can live for 30 years or more.

* African catfish: Can live for 10-15 years.
