I've had Betta fish many times over the years. They definately will fight other betta's but also anything with a "vail tail" like flashy guppies, or vail tail gold fish. Anything that's flashy, they take issue with. Otherwise, they require a warmer than usual tank temperature. Normally, they require 80 degrees' whereas other tropical fish do best at around 76-78 degrees. If they get too cold, they can become stressed and develope "swim bladder" and you'll end up watching them die a slow death. So if you are creating a "community tank", with other species of tropical fish, make sure you don't have anything too large or flashy. Even Angel fish are too fancy to share a tank safely with a betta. Just my humble opinion and experiences.
