How long do bettas usually live?

Marc Grover (Professional Aquarist) gives expert video advice on: Why aren't male bettas kept in the same tank?; Can I put a betta in my aquarium with other fish?; Where is the best place to put my betta? and more...

Typically bettas could live for a very short period of time if they've got problem. Typically though, it's nine months up to 2 years in captivity. In the wild, it could be a lot less amount of time due to the amount of environmental problems they've got to deal with and the natural territorialism and fighting with one another which you've eliminated when you keep them by themselves. But I've personally kept one over 18 months and I've had people tell me even two years could be typical. So nine months to two years is the widest parameter I'm giving betta fish.
