Betta Splendens

Siamese Fighting Fish-do they really fight???
Yes, male bettas will fight another male betta. They are usually fine with other non-aggressive types of fish, but never mix two males! But it is very interesting to show a male betta his reflection or a picture of another betta. He will put on quite a show for you! My betta was doing this tonight as I showed him pictures of other bettas. He flared his fins and puffed up his gills. He looked like a dragon! They are very beautiful fish!
