The average life expectancy of a betta fish is around four years. A betta fish has a maximum age of 12-14 years, and they have the potential to live up to 20 years. However, the life expectancy of betta fish depends on their diet and whether they are kept in captivity or the wild. In captivity, smaller tanks will not allow adequate swimming space, food, and oxygen levels for proper gas exchange, leading to poor health.

How Do I Understand If my Betta Fish is Dying?

Betta fish are known to live up to 20 years. So, if your Betta fish is not as active, does not eat, or has lost its color and vibrancy, you should take it to a vet for a check-up. If your betta fish has lost its color and energy, it could be dying. But if the fish’s appetite and swimming activity are normal, that means there is no need for immediate vet care. However, if these things have changed significantly from their average behavior, you should take them in for an examination.


Do Bettas Float When Dead?

Betta fish don’t float when dead; they sink. Though it is normal for betta fish to die, it is not customary to float. This is due to their poor buoyancy and lack of swimming skills. They tend to swim upward as a defense mechanism against predators instinctively. When a Betta dies, the body will sink and decompose on the bottom of the tank.

How Do You Keep a Dying Betta Fish?

Betta fish are popular because they are hardy and colorful. They are also very peaceful, making them a good pet for people who don’t want to deal with aggressive fish. To properly care for your betta fish, you need to make sure that their tank is large enough so that they can swim around and eat. The tank should also be set up to have proper feeding and oxygen levels.

It should also be cleaned regularly and have an appropriate substrate (dirt or gravel) on the bottom of the tank so that the betta fish can dig through it to find food. If your betta fish begins to suffer from poor health, start by cleaning the tank thoroughly before adding a new substrate. If your betta fish still isn’t doing well, consult with a vet about what could be wrong with it.

What Do You Do Behind Your Betta Fish Dies?

There are a few ways to care for your dead betta fish. In the wild, they may be eaten by other fish. If you choose to keep your betta fish in captivity, there are some things you can do to care for them after their death.

The first item you should accomplish is to quarantine your dead betta and prevent the spread of disease. The next step is to remove any evidence of the deceased fish, such as decaying flesh and blood. “Fish out of water” can help you dispose of your dead betta without contaminating the tank or filtration system with any signs of decay.

You can also utilize a plastic bag or a small trash bin liner to cover your tank and allow it to decompose naturally without spreading any smell. Your last option would be a burial at home in a shallow grave where they will not contaminate anything.


How to Care for Your Betta Fish

With proper care, a betta fish can live up to 20 years. Here are some tips for healthy betta fish care:

– Feed your betta fish with fresh, high-quality food. Avoid frozen and dried food as they aren’t typically high in nutrients.

– Provide adequate space for your betta fish to swim in. Minimum requirements are a 10-gallon tank with a mesh cover; however, you can also provide more space by adding decorations like fake plants, driftwood, and rocks.

– Add oxygenate to the water with an aerator or by using an air stone.

– Rinse your betta fish’s water frequently using a filter that allows for easy cleaning. This will help remove any toxins or waste in the water without disturbing the ecosystem of nitrifying bacteria that helps break down ammonia into nitrites. Then, it removes nitrates from the water and converts them into harmless nitrogen gas bubbles.

– Test the pH of your tank’s water regularly to ensure it stays at around 7.2; this is essential for preventing disease and keeping your betta fish healthy.

Common Betta Fish Diseases

Betta fish can suffer from a variety of health issues. Two of the most common are fin rot and ich. Fins rot is a skin disease that causes the fin to become dry and brittle. Fins rot can be treated with topical medications, but it may require surgery for severe cases. Ich thrives in crowded tanks and is contagious to other fish. It affects the gills and fins and can lead to organ failure if left untreated. The most common betta fish diseases are fin rot, ich, bacterial infection, or dropsy (a condition characterized by swelling due to fluid in the body).



The life expectancy of a betta fish varies greatly depending on the size of the tank they’re kept in, the type of food they’re given, and the quality of care they receive. Because of this, it’s hard to provide a definitive answer on the average life expectancy of a betta fish. However, a betta fish should live for at least three years with proper care.
