Short description

Keep Betta anabatoides in a well planted tank with hiding places. They prefer soft and slightly acidic water with a low flow. Giant bettas are a peaceful species and the male may grow up to 5 inches in length. They are a relatively easy species of fish to care for but they still require high water quality as does all fish species so make sure that they have an adequate filtration system and regular water changes are performed. The giant betta are believed to be the result of genetic breeding from Asia but it is accepted that they can be cared for along the same guidelines as Betta spendens with the only obvious difference being the different breeding habits. They are sensitive to poor water quality and diseases so extra care should be taken with aquarium maintenance, a common cause of death is often related to digestive issues when the gut becomes inflated when they can no longer pass through their waste and they are often victims of bloat where there stomachs will swell. Unfortunately the Giant betta is prone to disease if the water quality is not kept to the highest standard so these fish should not be kept by novice fish keepers. They are also badly affected from any form of parasite so care should always be taken with introducing new tank mates. It is advised that any new additions to the aquarium should go through a quarantine period to make sure that they do not pass on any disease or carry any parasites.

Food and feeding

The Giant Betta will accept quality flake but prefers to eat live or frozen food. Blood worms, brine shrimp, daphnia and white worms are ideal. Small meaty foods also help to clear out the digestive system as they are easily broken down, this will ensure that any future digestive problems are avoided.


Males will be more colourful than the females with a yellow tint to their anal fin.


Giant betta is a mouth brooding species, the male will brood the eggs once the female has laid. Any eggs the male has missed will be picked up by the female and spat towards the male for him to hold. The female will play no more part in raising the young. When the fry have been released, they can be fed on newly hatched brine shrimp. These are not the easiest of Bettas to breed mainly due to their size, larger breeding tanks may be required but they are not impossible to obtain fry from with patience.
