Betta fish (Siamese Fighting Fish) typically lives about three to five years but you should not expect that much longer lifespan while you keep it in captivity. When you bring one such species from the store, it is likely that the fish is already one year old. The male betta fish do not grow its colors and fins until they reach one year. Generally, betta fish cannot survive for more than one year to be precise. Nonetheless, you can certainly extend the betta fish lifespan while taking good care of it and feeding it a healthy diet.
