The life span of a betta fish varies, and they can live anywhere from 3 to 10 years. The environment in which they are raised is the biggest determining factor.
Three years is the normal length of time a betta lives. Giving them the proper food and habitat can help prolong their life. While bettas can live in small aquariums, a 5-gallon or larger tank is preferred. This gives them plenty of room to exercise and stay healthy. In addition, a food made specifically for bettas ensures they receive the proper nutrients. Following these tips will help the betta live for the maximum length of time.
