Giant Betta Fish


What are Giant Betta Fish?

Giant betta fish are scientifically called Betta anabatoides. They belong to the gourami family and the Macropdusinae subfamily. These rare fish live in freshwater and are native to Indonesia Borneo. Giant betta fish tend to be less aggressive than standard Siamese fighting fish. Often giant bettas are selectively bred by choosing the largest male and female of betta splendens type available and breeding them. This selective breeding creates giant betta fish.

What is the Difference Between a King Betta and a Giant Betta?

King betta fish (betta imbellis) are normal sized bettas. Giant bettas are true to their name and grow 3 to 5 inches long or more. 

Can Male Giant Bettas Live Together?

Even though these fish tend to be more docile, males should still be kept separate. You can pair them with other fish like tetras, rasboras, guppies, corydoras, and mollies.

How Big Do Giant Betta Fish Get?

These large bettas usually grow about 3 to 5 inches long, but on occasion these amazing tropical fish can grow up to 7 inches long!

What Size Tank Does a Giant Betta Need?

We recommend a 5 gallon tank for a single Giant betta fish. Choose at least a 10 gallon tank if you are considering a few companion fish.

How Long Do Giant Betta Fish Live?

Giant betta fish live about 2 to 3 years. They tend to have a slightly shorter lifespan than standard betta fish, but can live up to about 5 years if they have excellent care and are well bred. 

What Do Giant Betta Fish Eat? 

These big bettas eat the same diet as standard bettas. They can be fed commercial pellets or flakes or fresh, freeze-dried, or frozen foods like brine shrimp, daphnia, mosquito larvae, fruit flies and mealworms. Always be sure your live foods are from a reputable source and free from chemicals, parasites, and bacteria.

How Much to Feed Giant Bettas

Not only do these pet fish grow larger than regular betta fish, they tend to grow almost twice as quickly when they are young. So a 4 month old giant betta is likely to be about the size of an 8 month old standard betta. These fish need more food too. They will consume almost twice as much as traditional bettas. For example, if you feed pellets where you would normally feed 4 or 5 to your adult betta, an adult Giant betta will need 8 to 10 pellets or pieces of food. Never overfeed your betta. Bettas eat quickly. If you notice leftover food after a couple minutes cut back on how much you are feeding your betta. Feed once or twice daily on a consistent schedule.

How to Care for Giant Betta Fish

Other than the need for a larger tank and more food, Giant betta fish require the same care as other betta fish. 


Choose a tank that is at least 5 gallons and a water heater that keeps the temperature between 76 and 81 degrees Fahrenheit. Water should always be treated with a water conditioner before being added to the tank. Keep the tank clean and healthy for your giant betta with routine cleanings. Feed your fish once or twice daily with a high quality food. Read more information on Betta Fish Care.

How to Breed Giant Betta Fish

You will need 2 tanks or a large tank with a divider. Choose a quiet location with minimal traffic. The tank should either have a very gentle filter or no filter at all to avoid disturbing the bubble nest. The ideal water temperature for breeding is 78 degrees Fahrenheit. The tank bottom should be kept bare. Be sure there are a couple hiding places for your fish to go to. Some males prefer a leaf or some type of floating decor to build their bubble nest under. Slowly introduce your male and female to be sure there isn’t any unwanted aggression.


Betta anabatoides are mouthbrooders so with these fish you will not see a bubble nest like with betta splendens. The pair will breed and the eggs will drop to the bottom of the tank. The male and female will pick up the eggs and put them in the males mouth. He will care of the eggs and fry until they are ready to be released, which is usually 7 to 10 days.
