How long can a betta fish live?

A betta fish (Siamese fighting fish) generally lives about 2-3 years, though the exact lifespan depends on its living environment and how it is cared for. There is also a difference between the sexes: male bettas usually outlive females.

To help a betta live longer, it is best to keep it alone, maintain the water temperature between 22-24 degrees C, feed it properly, and keep its living environment clean and healthy.
