What is the life span of a Betta fish?

I went to the pet store and one of the people who worked there told me that some betta fish last a year or two, but in some cases you get ones that last like five years. My sister got a betta fish that lasted five years and wouldnt die, even when we didnt feed it...

Bettas have an average life span of 3-5 years, with several reaching 7 (the record is 9 years). While not exactly "long", it's a longer life span than a lot of other aquarium fish. Not everyone is as successful in keeping them because they don't keep them in the correct conditions. They buy the "betta vases", or keep them in bowls just a little larger than the cups in which they're sold. No fish will live very long under these conditions. First, a betta should have at least 2.5 gallons of water. They also should have a heater unless they're in a room that's warm enough to keep their water temperature 76-86oF. Gentle filtration keeps their water cleaner, and it gives them a little current to swim against for exercise (I read that one of the 2 bettas that lived for 9 years lived at a university where students were paid to exercise the fish by "chasing" it around in its tank - fish should have exercise the same as people to stay "fit"!). Regular water changes are a must! in a 2.5 gallon filtered tank, you should change 25% of the water once a week using a gravel vacuum. If the fish is kept in a bowl without a filter, you should do 100% changes every 2-3 days. The difference is because the gravel and dissolved oxygen added by the filter allows bacteria that convert your fish's wastes (ammonia, which is toxic) to nitrate, which your fish can tolerate in moderate amounts. In the bowl, there's not enough water movement to the bottom to keep the bacteria alive, and the ammonia builds up to the point it poisons your fish. It's also important to give them a good, varied diet (pellets, bloodworms, daphnia, mosquito larvae) but not to overfeed. Excess food that decays in their water also is a source of ammonia.

Overall average= 2-3 years

Average of a betta with good care= 5-6 years

Oldest betta= 13 years

The numbers you will usually find is about 3-5 years, though you'll find stories of bettas who lived up to ten years. Keep in mind that bettas at the pet store are already about 6 months old, depending on the provider. Of course, the better the conditions are for the fish, the longer he or she will live.

Normal life span is 3-5 years, however they don't go to the store until their fins have grown in so in some cases they could be over a year old at that point.

most people keep them in cruel little bowls and they last 6 months maybe a year tops. In a nice 5+ gallon heated and filtered aquarium they can live up to 7 but usually around 3 or 4 years

2 years

first of all is it a male or a femal. male betta live for 2 to 3 years, female betta live for 4 to 5 years. the tanks size does not make a difference, what does make a difference is the health and nutrition of the betta.

Normal for me has been 4 or 5 years. I've kept them in 10 gallon or larger tanks.

The normal lifespan is about 2 to 3 years.

A few of them live as long as 5 or 6 years.

Since they are usually about a year old when they are sold in the pet shop, you can expect yours to live for a year or two after that if you care for it well.
