Is keeping betta fish in an aquarium with other fish a good idea? The betta fish or Siamese fighting fish is known for the territorial aggression it shows. Keeping two male bettas in the same tank is not advisable as they will end up fighting with each other. But can a betta, male or female, be kept in a community aquarium with other fish? Yes, the betta is compatible with certain fish species. It can live peacefully with some kinds of fish. But keeping in mind the aggressive temperament of your betta fish, you need to be careful while choosing tank mates for it. You will have to make a list of fish that can live with bettas and then decide which other fish species you can choose as tank mates for your betta.

The ideal tank size for a single betta fish is 5 gallons or more. If you decide to keep other fish along with the betta, the tank size should definitely be more than 5 gallons, say 15 to 20 gallons or the issue of territorial aggression will come up. In a 10-gallon tank, you can house the betta with 3-4 other fish. So choose the tank mates depending on your tank size.
