According to the data, the life span of betta is generally 3 years. There are many factors that affect the life span of betta fish, such as innate physique, living environment, food fed, water quality and so on. In congenital constitution, the life span of male betta fish is generally 3 to 6 years, while that of female betta fish is only 2 to 3 years. If the water quality of fighting fish is poor, the life span of fighting fish will be shortened.

If you give betta fish the same food for a long time, it will also make betta fish undernourished, which will lead to malnutrition and affect their life span. If the living environment of betta fish is poor and betta fish will be particularly uncomfortable, it will also greatly shorten the life of betta fish.

If you want betta fish to live for a long time, you should pay special attention to the way of raising it. In daily feeding, it is best to mix a variety of foods, which will make the nutrition richer and more comprehensive, so that betta fish will grow well. In terms of water quality, it is necessary to change more water to ensure clean water quality, which also prevents betta diseases to a certain extent.

If you want your own betta fish to live longer, it is best to choose more male betta fish fry at the beginning. Because male betta generally lives longer than female betta.
