Fact of the Day: Terrible Tank Buddies

The betta fish (more specifically the B. splendens variety) are often known as the world's worst underwater room-mates. Males will immediately try to attack one another, or attempt to hurt their own reflection in a mirror. Because of this they are better kept in separate tanks, though some live with different and larger breeds of fish that don't pose as a visual threat to a betta. Males don't usually attack females on first sight, but after mating they have been known to battle each other.


  1. They are beautiful...too bad they can't get along with each other :)

  2. Bad act from beautiful fish!

  3. They're really pretty, though...

  4. I wonder why they are so brutal to each other, even the males and females.
