Can two betta fish be kept together?
With adequate room, many can be housed together. However, if the tank becomes too crowded, females may start showing territorial behaviors as well. Do not mix males and females in the same tank, other than temporarily for breeding purposes.
Do betta fish eat themselves?
Remember, they can eat themselves to death if you aren’t careful. Betta fish are inquisitive by nature, and they need an exciting environment with plenty of things to investigate in order to be happy and active.
Do betta fish hurt each other?
Unless they’ve been specifically bred for aggression — or they occupy a small space with other bettas — most bettas will nip at each other, but they won’t necessarily fight to the death. Fighting behavior is much more common in male bettas, especially if they’re defending their territory or their food.
