Fat: Fat is an important energy source for betta fish, but it should be fed in moderation. Too much fat can lead to obesity and other health problems. Betta fish should be fed a diet that is low in fat, such as live food, frozen food, or high-quality pellets.
Variety: Betta fish need a variety of foods in their diet to stay healthy. Feeding your betta fish a variety of foods will help to ensure that it is getting all the nutrients it needs.

By feeding your betta fish a nutritious diet that is high in protein and low in fat, you can help to extend its lifespan and keep it healthy and happy.

3. Exercise

Exercise is an important part of a betta fish's life. Betta fish are active swimmers, and they need plenty of space to swim around in order to stay healthy and happy. A tank that is too small can restrict the betta fish's movement and lead to health problems, such as obesity, stunted growth, and fin rot.

The ideal tank size for a betta fish is at least 5 gallons. This will give the betta fish enough space to swim around and explore. Betta fish that are kept in tanks that are too small are more likely to develop health problems and have a shorter lifespan.

In addition to providing a tank that is large enough for swimming, you can also provide your betta fish with other opportunities to exercise. For example, you can place floating plants or toys in the tank for the betta fish to swim through. You can also feed your betta fish live food, such as brine shrimp or bloodworms. Live food will encourage the betta fish to swim and chase after the food.

By providing your betta fish with plenty of exercise, you can help to extend its lifespan and keep it healthy and happy.

4. Stress

Stress is a major factor affecting the average lifespan of betta fish. Stress can lead to a weakened immune system, making the fish more susceptible to diseases. It can also cause the fish to lose its appetite, which can lead to malnutrition and stunted growth. In severe cases, stress can even lead to death.

There are a number of things that can cause stress in betta fish, including:

Overcrowding: Betta fish are territorial fish, and they can become stressed if they are kept in a tank that is too small. A good rule of thumb is to provide at least 5 gallons of water per betta fish.
Poor water conditions: Betta fish are sensitive to water quality, and they can become stressed if the water in their tank is not clean and free of toxins. It is important to change the water in your betta fish's tank regularly and to use a water conditioner to remove chlorine and other harmful chemicals.
Other fish: Betta fish can be aggressive towards other fish, and they may become stressed if they are kept in a tank with other fish that are too large or too aggressive. If you want to keep betta fish with other fish, it is important to choose tankmates that are compatible with bettas.

By avoiding stress factors like overcrowding or poor water conditions, you can help to extend the lifespan of your betta fish and keep it healthy and happy.

5. Genetics

The average lifespan of a betta fish is 2-5 years, but some breeds may live longer or shorter than others. For instance, plakat bettas, known for their shorter fins and stockier build, tend to have shorter lifespans compared to long-finned breeds like veiltails or halfmoons. These differences in lifespan can be attributed to genetic factors that influence the fish's overall health and susceptibility to diseases.

Selective breeding practices have played a role in shaping the genetic diversity and lifespans of different betta fish breeds. Breeders have focused on specific traits, such as fin length, body shape, and color patterns, which can inadvertently impact the fish's overall health and longevity. For example, long-finned breeds may be more prone to fin rot and other health issues due to the increased surface area of their fins.
