betta fish like at least a 1 gallon tank (nothing smaller) > They can live in a community tank but with no other bettas.
Male betta fish are typically aggressive and territorial, so they are best kept alone in a tank to prevent fighting with other fish.
Bettas are typically aggressive and territorial fish, so they may not live peacefully with other fish in the same tank. It is important to research and carefully select tank mates that are compatible with bettas to avoid any conflicts.
Decomposers are microorganisms. They live in plant material in the fish tank,
