How do i know what other fishes to put with my betta or do i just not put any other fish since they are violent ?

Best Betta Fish Tank Mates:

Cory catfish.

Neon and ember tetras.

Ghost shrimp.

African dwarf frogs.

Guppies.

Kuhli loaches.

Bettas usually attack scales, gills and tails and will respond if bitten by aggressive fin nippers like angel fish or red tail sharks, Dr. Tepper says. Goldfish and dwarf gourami should also be avoided, as well as fish that are larger than your betta or have similar fins.

Consider these fish and other aquatic animals to put with bettas:

Cory catfish

Neon and ember tetras

Ghost shrimp

African dwarf frogs

Guppies

Kuhli loaches
