Top 5 Things That Affect Bettas Lifespan

Owning betta fish seems to be getting more and more popular these days. It’s probably because of how beautiful they are compared to other freshwater fish, and how easy they are to maintain, at least in my opinion. While an average betta fish lives for about 3 years in captivity, bettas lifespan can be significantly increased provided that you take care of certain important things.

How Can Bettas Lifespan Be Improved?

Below are the top 5 factors that can affect your betta’s chance of survival:


The breeding process has a significant role in determining the betta fish life span. Provided that your fish was not used for the purpose of breeding or spawning, it should be able to have a longer life span than the average two years. Try to find out as much as you can about the betta you are planning on buying. Don’t be afraid to ask questions from the breeder or pet store you are buying the betta fish from. The more you know about it’s history, the better.

Another important factor that defines the life span of your betta fish is the strain that it was put through at the pet store where they were being held waiting for their new owner. A lot of stores that you can buy betta fish from fail to meet the basic requirements of the fish, so it is important that you consider the strain that it may have been put through before you buy him or her. Do some research on the pet store where you plan on purchasing your betta from to make sure you are buying from a reputable place.


It’s widely known that the bigger the aquarium, the better the chances of increasing your betta fish life span. The more the space that it is given, the longer it is going to live. As per the research studies, it has been claimed that in order to increase the lifespan of the betta fish, it is ideal to keep it in 5 gallons of water at the very least. Any smaller than that and you are taking a risk in losing your betta at a younger age.



There is no argument over the fact that betta fish depend on the quality of diet that they are being provided as well. One thing you can control is the amount of food you give him or her. Avoid over feeding since it may lead to obesity and an earlier than expected death. Recommended food for betta fish include pellets, blood worms, and brine shrimp.

Water Conditions

The condition of the water that your betta lives in also plays a major role in determining how long your betta will last. Don’t forget to clean the water at least once per week. If you aren’t sure how to do this and what’s involved, we covered the details in our post called How to Clean a Betta Fish Tank.

Some people believe that the type of betta can be a factor in determining the life span of a betta fish. For instance, it’s believed by many that the crown tail and half moon can live longer compared to the rest. However, there is no scientific proof behind this. As you can see, there are lots of factors that can affect bettas lifespan. Although there is no guarantee in life, if you keep these factors in mind when buying and caring for your betta, it should live a long and plentiful life!
