The average Betta Fish can live for three years if kept in optimum conditions. But some owners who take good care have seen their Betta fish live for up to 5 years.
In the wild, the Betta species live in slow-moving streams, canals, and rice paddies, and their life span is typically less than three years.
There are a few reasons for this;
The first is that, in their natural environment, Betta fish are more likely to encounter and engage with other male Bettas, which can increase their chances of becoming injured or killed.
Second, The increasing pressures on the Betta’s natural habitat from pollution and loss of habitat due to increased farming development all significantly decrease their lives.
This shortened lifespan has resulted in the Betta fish being declared a threatened species by the IUCN.

Let’s move on.
How To Make Your Average Betta Fish Live Long
The lifespan of a Betta fish can be significantly increased by doing a few simple things; they are as follows;
- Tank Size
- Maintain the Ideal Tank Temperature
- Water Changes & Water Quality
- Include a Lid and Space at the Top
- Use An Aquarium Filter
- Include Plenty of Places to Hide
- Select the Right Tank Companions
Each of the items noted above is covered in detail in our post, The 7 Fundamentals of the Ideal Betta Fish Tank.
Let’s review the top 5 most important factors that impact Betta fish health.
1. The Right Tank Size: The Bigger, the Better
Many people believe it’s perfectly okay to keep them in a small fishbowl or vase, which is hardly enough room for swimming, let alone the other benefits of a healthy aquarium.
That’s often how they’re sold in pet stores, and those stores can sell you a fish more easily if they tell you that you won’t have to buy a large tank and other equipment for your beautiful Betta fish.
But even though Bettas can survive in little tanks, it’s not ideal for the fish. If you want a happy, healthy, and long-living Betta fish, you shouldn’t have a tank smaller than a 5-gallon, and 10 gallons or more is best.
A 5-gallon tank will give your Betta more room to swim and get exercise, and there will also be more space to add plants and other hiding places that will make your Betta more comfortable.
It’s also easier to maintain a larger tank because you won’t have to change the water a lot, and you can add a filter to help manage your water chemistry and filter out debris.

2. The Right Tank Mates
Betta fish are also known as the Siamese Fighting Fish.
And for a good reason.
When kept with other male Betta fish, they have an aggressive side and can be very territorial, which can cause them to nip the fins of other males or, worse, fighting, which can often lead to injury or death.
Female Bettas, on the other hand, can be in the same tank without too many problems. If you want to keep them with other fish, make sure you try out some of these great Betta tank mates.
3. Water Quality And Water Temperature
Betta fish originated in Southeast Asia’s streams and rice paddies, so they naturally prefer warmer temperatures.
Your betta fish water should be at the right temperature, around 76-82 degrees F (24-27 degrees C).
Too cold, and they can become sluggish and prone to disease. Too high or low a PH, they will die a slow, painful death.
Our post about Betta Fish Tank Temperature shows you exactly how to maintain the ideal water conditions for your Betta fish.
To create the ideal Betta fish tank environment, you’ll also need a heater and thermometer set up to monitor your tank temperature and keep it consistent.
If the temperature is too low, your Bettas immune system will suffer, and he’ll be more prone to disease.
Too high a temperature and your Bettas metabolism could accelerate, causing him to age too quickly.
Adding a heater to your tank will ensure you keep the temperature in this range so your fish won’t be too stressed from sudden temperature changes.
Note: If using tap water for your tank, use a tap water conditioner to ensure any harmful chemicals are removed before adding your Betta to its tank.
Completing regular water changes and maintaining the right temperature will go a long way towards keeping an energetic Betta fish.
4. Maintain A Healthy Diet
Using the right betta fish food is critical in adding years to your Betta life span.
A Betta’s diet should be protein-rich and meaty. The best is for pellets, frozen or live bloodworms, daphnia, and brine shrimp.
Read our post What do Betta Fish Eat? Then, we’ll show you all the different types of food that a Betta fish should eat and which ones are the best.
Make sure you provide the proper diet, don’t feed them too much, and you can add several years to your Betta fish.
5. Buy a Healthy Betta
When you head out to buy your Betta, there are a few things you should look for when selecting a healthy fish.
- Shop at a local fish store. Often big chain stores neglect their fish, and this is well documented. Bettas sold in tiny cups are a dead giveaway of poor fish practices.
- Are the tank conditions they are kept in, is the water clean, or is it dirty and cloudy?
- Is the fish active and not laying still on the bottom of the tank.
- Find fish that have bright colors and avoid fish that are pale, have torn fins, scratches, or have cloudy eyes.
- Use Plants to Provide Oxygen
Plants in your aquarium produce oxygen and absorb carbon dioxide from fish during the day. At night, the reverse happens, which is also vital to having a well-maintained tank.
Tiny algae can settle on the plant leaves and clean the water. Additionally, the plant can help keep the tank clean by reducing the toxins in your tank produced from the waste of your fish, requiring fewer water changes.
Lastly, when plants are healthy, they give off small amounts of oxygen through their root systems, which will prevent your substrate from decaying.
All of these items make your entire tank healthier for fish and plants. Without plants in your aquarium, the processes above cannot occur.
Plants are a vital part of an aquarium when you’re looking to keep a balanced fish tank.
They also allow for proper shelter and security for fish and make your tank feel more natural, leading to calm and stress-free fish.
