🥇🐠 How Long do Betta Fish Live

How Long do Betta Fish Live? The average lifespan of Betta fish, or betta splendens, is 2 to 4 years in captivity, for both males and females. Some aquarists said they kept a fighter for 6 years! The lifespan of a fighting fish depends on several factors.

Make the right choice from the start

If possible, buy your fighter from a local breeder instead of a pet store. These stores sell male fighting fish when they are about a year old, and females when they are about six months old. This will affect the length of time you can admire your fish.

It is always difficult to know how the fish were maintained when purchased from a pet store. They may have been subjected to cramped, overcrowded aquariums, and regularly given medication to prevent stress-related illnesses.

You should therefore be particularly vigilant when buying and buying a healthy betta. Choose a betta with bright colors and alert behavior. If it is a male, check to see that it displays when it is in front of another male. It should not have ripped, ruffled scales or white spots.

Life expectancy of a fighter in a ball

A fighter’s lifespan will always be significantly reduced if kept in an unfiltered, unheated ball. This is especially true if the volume of the aquarium is less than 10 liters. Pet stores display fighters in small containers due to their aggressiveness and territorial nature, and to save space. It is a temporary habitat since cohabitation is delicate with females and other fish, and impossible between males.

Pet stores also sell small aquariums of less than 10 liters (or even only 2 liters!) Specifically for combatants. Flee them like the plague! This is not suitable for these fish and would reduce their life expectancy.

How to take care of a betta fish?


It is recommended to choose an aquarium with a volume of 20 liters to have a happy and healthy fighter. If you are constrained by space, a 10 liter aquarium is a vital minimum. A smaller aquarium will seriously affect the life expectancy of your fighter, because the chemical balance of the water will be very precarious there and the fighter will not have enough places to hide: he will be stressed.

If you are in doubt about the size of the aquarium, always go for the larger one.

We have prepared a selection of the best pest control aquariums currently on the market for you, and there is something for every price.
Bettas need hiding places to feel safe, so make sure you have enough plants (real water plants if possible) or decorations. Also make sure your aquarium has a lid, as fighting fish will jump and may end up on the ground.


Fighters need a specific diet rich in protein. Some fighting fish are particularly finicky and will not even touch the food intended for tropical fish because it does not meet their needs.

It is therefore necessary to focus on foods intended for combatants, but also to supplement this diet with other foods rich in protein, such as bloodworms or artemia. These can be found lyophilized, frozen or alive.

In the wild, fighters have access to many prey and are active carnivores. In captivity, you need to replicate their environment as much as possible, and that also means nutrition. Avoid overfeeding them, as this can also lead to complications.

Another main cause of reduced lifespan is poor water quality. Don’t use distilled water because it has been stripped of the nutrients and minerals fighters need to be healthy. Use tap water if its ph and Gh is 7. If your pipe water does not meet these parameters, choose mineral water. The Volvic is quite suitable for combatants!


Small aquariums require more frequent cleaning because the balance is unstable and waste has a greater impact on water quality. Ammonia builds up as you feed your betta. The resulting illnesses can harm your fish and often results in death due to poor water quality.

Keep your aquarium clean by regular water changes, 3 water changes of 20% per week if there is no filter, otherwise one is enough. Always prefer to use a filter to reduce ammonia, nitrites and nitrates. Indeed, even if you have the impression that the water is clean, a filter is very useful to remove the chemical components which can become toxic for your fish.


Fighters are tropical fish and need a constant water temperature of around 24 degrees. Living rooms have fluctuating temperatures, so plan for heating, if possible with an integrated thermostat in order to stabilize the temperature.

Avoid sudden temperature changes and avoid colder temperatures at all costs. Prolonged exposure to temperatures below the recommended temperatures can harm a fighter’s natural immune system and lead to listlessness and refusal to feed.

The life expectancy of your fish depends on your knowledge!
If you already knew the above information, it means you’ve already educated yourself! If this is not the case, you will find all the information you need to take good care of a fighter in our ebook dedicated to this fish .

Some fighters are more resilient than others. Even with the best maintenance in the world, every fish is still different and it’s usually impossible to know how they’ve been treated until you buy them. With the right knowledge and passion, you can certainly expect your betta to live 2-3 years with you.

What fish can live with bettas

The Betta Crownetta is aggressive towards other fish, it’s definitely not a neighbor!

Make up their space and their bettas love being territorial.

Never stock a male Crowntail with another in the tank. As adults, they will fight until one dies.

Betta Crowntail prefers to be alone if you want to show your friends and live in your aquarium using a little variety of fish, you have two options.

Recomendations: The crow’s beak will harm any fish that reflects its behavior; aggression, dominate, territory and greater.

If you are looking for compatibility, try the fish that love swimming in the cloud of another layer in this aquarium. Since the aquarium’s upper clouds and the Crowbill are centrally located, we are looking for calm and calm bottom dwellers:

  • Neon tetras are a really great alternative
  • Guppies – they are extremely fast and will get out of the control of these bettas
  • Shrimp (eg red cherries or ghost cherries)
  • Frog (example: African dwarf frog)

Do not place them if you are bringing a Betta into the aquarium.

Use floating in this tank for 30 minutes with the Betta inside, cup or cup of Betta.

See that he behaves through fish. In the event that your Betta Crowntail is too competitive (bring swollen fish, for example), it shouldn’t come out of the tank.

While in the tank, make sure the betta is aggressive with other fish.

What do betta fish eat ?

The fighting fish are strict carnivores, so it is important to provide them with a specific diet, not food for tropical fish.

Several types of foods are available. Choose food in the form of seeds, which will be your fish’s main food. Personally I use the betta dennerle booster.

To provide more protein to the fighting fish, you can feed the fish raw, frozen or freeze-dried food two to three times a week: bloodworms, arteries, crustaceans …

How much food for bettas – How often do you feed a betta fish?

Fish have very small stomachs, and they must eat their food within two minutes to avoid contaminating the aquarium. So, give the fish 2-3 capsules per feed.

Feed once or twice a day, fasting one day per week.

How long can Betta Fish go without eating?

Your fish can last up to two weeks without eating. If you plan to be away for less than two weeks, fast. Using an incorrectly tuned dispenser or leaving it with an “empty block” will do more harm than good and possibly kill it by contaminating the water. When you come back, feed it as usual.

Do betta fish sleep?

The fighting fish sleep like all other fish, to a resting state, generally close to the stand (glass, platform, base, etc.). Just standing still can allow you to see that it is resting. Fish wake up to your slightest movement or light.
