Betta fish or Siamese fighting fish are one of the most widely kept and loved tropical fish. Often seen in smaller containers and even bags (Not recommended), these stunning fish are prized throughout the world, but How Long Do Betta Fish Live?
Let’s take a look in more detail at the Betta fish and see not only how long they live but also the 3 simple steps you can take to ensure they live a long and happy life.
How long do betta fish live? Given the best aquarium conditions and a good diet, the Betta Fish (Betta splendens) which are part of the Gourami family can live on average 3-5 years. Often sold at around 6-12 months you can expect to keep one for around 2-4 years.
Can You Help Your Betta Fish Live Longer?
Like most living creatures that we keep as pets, we have a duty of care to ensure they have everything they need to thrive.
We need to ensure they have the very best water conditions, food and chemistry to replicate the conditions they would find in the natural habitat
DID YOU KNOW? The oldest reported Betta Fish came from Japan and is said to have lived for 9 years!
Going the extra mile when it comes to feeding your Betta Fish could make the difference and extend their lifespan. I bet the Betta fish that lived for 9 years wasn’t just fed flake food all its life.
How Long Do Betta Fish Live?
Because Betta fish come from the Gourami family their natural lifespan isn’t long at all. Most Gouramis will only live for 6 years.
In an aquarium, the lifespan of a Betta fish is longer than in the wild. Because betta fish are labyrinth fish, they will often swim near the top of the water which makes them easy prey for birds and other predator fish.
In an aquarium, we can control their environment and the tank mates they live with making it a safer place to live.
There is also no risk of water pollution in an aquarium (well, hopefully not).
In the wild, the males are not separated from each other and fights often occur. Hence, their common name Siamese Fighting Fish. This has an effect on population numbers and lifespan.
Where Do Betta Fish Come From?
Betta fish are native to native to Thailand, Cambodia and more recently to parts of Brazil, Malaysia and Singapore.
Their natural habitats are shallow riverbeds, canals and streams and rice paddies.
Bettas were first kept in captivity in Thailand (formerly Siam) over 150 years ago. They were kept as fighting fish to gamble with and bet on. It became so popular that the King of Siam starting taxing them.
FUN FACT: Children collected Bettas from the rice paddies and started keeping them in jars to watch them fight. Betting then became common place. Hence their name, Siamese fighting fish.
The fish was named Betta meaning “beautiful warrior” by Charles Tate Regan who renamed them Betta
They first came

3 Ways To Increase Betta Fish Lifespan
There are a number of things you can do to extend and improve the lifespan of your Betta Fish. We have narrowed it down to the three most important in our opinion.
These are simple steps you can take to improve the conditions your Betta fish live in captivity and will help your Betta to try and beat the world record age of 9 years!
1. Water volume and conditions
You will often see that Betta fish live in small containers and even jars. Siamese fighting fish possess a specialized labyrinth organ on the top of their head which allows them to take in surface air, and this supplements oxygen in the water.
They cannot survive on surface air alone (they also need oxygen in the water) but it is a necessary form of oxygenation – without surface air oxygen they can drown and die.

These fish are often displayed in small tanks or jars in-store due to the fact that males fight and cannot be kept in the same aquarium. It is not possible for stores to have a tank for every Betta so they keep them in small display tanks.
This is not a longterm environment and oxygen and freshwater is replaced daily. In the home aquarium, you should consider keeping females and a single Male in your aquarium.
Provide the same water conditions and chemistry that you would for any other tropical fish. Do not treat them with any less respect. The perfect water conditions are listed below. Provide your Betta fish with the correct water parameters and they will live for at least 3-4 years
|Scientific Name||Betta splendens|
|Temperament||Peaceful-Unless 2 males are being kept together|
|Water Conditions||75-86° F, KH 0-25, pH 6.0-8.0|
|Tank Level||Swims at all levels but mid-top mostly|
|Ideal Foods||Betta colour enhancing Flake foods, mini betta pellets, Live foods|
|Ideal First Fish?||Yes, hardy, inexpensive and easy to feed|
The perfect diet for a Betta fish consists of dried flake foods, freeze-dried meaty food and live foods.
A perfect balance of vitamin-enhanced dried foods and fresh live foods such as bloodworms will ensure your Betta has all the nutrients and vitamins they need to thrive.
A poor diet is the quickest way to shorten your Bettas lifespan. No one would want to live on one type of food for their whole life, Right? So, why should your Betta?
There are a number of specialist Betta foods on the market. Some have been designed to bring out their colors and some to provide the best possible vitamins to ensure your Betta lives a long life. We highly recommend Hikari Betta Gold Mini Pellets which contains Stabilized Vitamin C which supports their immune system and p
3. Keep males separate
Males should always be keep away from other males or inevitably fighting will break out and they often fight to the death.
One male can be kept with many females in a community aquarium without concern. Females are less pretty and don’t have large colorful fins like the males and are therefore less popular.
Females don’t fight. Only the male species will fight with each other.
Keeping one male per aquarium is a good way to ensure they have no other Siamese fighting fish to worry about.
Betta fish with their long fins are susceptible to being nipped by other fish. They stand out in the aquarium with their colorful fins and are therefore an easy target by others. Despite their common name ‘fighting fish’, they often don’t stand up to other predators in the aquarium and can suffer from bullies.
Add one male to a peaceful community aquarium and you’ll be giving them the best chance of a long and happy life.
How To Increase The Lifespan Of A Betta Fish
When you visit your local aquarium store and see the many different varieties on show (over 78 varieties are commonly available), they are already 1 year old.
On average you will not see a Betta fish for sale less than 1-year-old. This is due to the fact that younger than 1 year they don’t display all their beauty. Therefore stores can’t sell them as easily.
So Bettas are bred in captivity and grown until they are one year old and start to display their true beauty. Unfortunately for us buyers that’s almost 20% of their lifespan gone.
If you want to ensure you get the longest lifespan from your Betta you should look to buy privately from a breeder and buy them young. That way you get at least an extra 6-12 months of enjoyment.
As mentioned before Betta are seen to be kept in smaller display tanks or even jars.
We highly recommend you keep your Betta in a community aquarium with other fish or at least in an aquarium 5 gallons or more.
Ideally, we like to see a male and female in a larger mixed community aquarium but if you just want to keep one stunning male then at least provide them with a spacious aquarium to enjoy.
My son has one male and several community fish in an aquarium similar to that below and it looks stunning. It is planted and has some floating plants. His Betta is often seen not moving which scares him. But it’s just his male building a bubble nest underneath the floating plants like many Betta do. Don’t panic!
You will see lots of fancy-looking aquariums online labeled as ‘Betta Fish Tanks’ but look at the water volume. Most are very small and will require you to make regular water changes to ensure your Betta has the best water conditions possible.
In very small aquariums it is difficult to control and monitor the water parameters. An aquarium of 5 Gallons or bigger like the one above is easier to keep and look after.
