Tank compatibility

Bettas are relatively peaceful fish. Their aggressive behaviour shows when mixed with other Bettas or anything with long, colourful fins that the Betta may confuse for another Betta. Males should not be kept with other males or females. Females develop a hierarchy so should be kept alone or in groups of 4 or more in a minimum of 10 US Gallons (37.9L). Males should only be kept with females during the brief breeding period. Bettas should not be kept with aggressive tank mates such as Gouramis or Cichlids or with fish that can nip their long fins such as Danios, Tetras or Barbs.
