As long as the other fish aren’t in the same family as the Betta like Gouramis or have long flowing fins like Guppies he should get along with just about anything.QUOTE]
I disagree, I have kept many (male) bettas with gouramies, with absolutely no problems. Right now, I'm even keeping (male) bettas with fancy guppies, and even though the bettas did chase the guppies for the first day at the most, I have not seen any other problems.
Thsi isn't to say that EVERY betta will get along with those particular fish, I know for a fact that the betta of another forum member has broken/bitten guppies in half, but not ALL bettas are THAT bad. If the betta were to atack them, P_W has a tank the betta can go in, so it's worth a shot. Just be sure to keep a watchfull eye on the tank.
