Take my word - simply drop the idea.
Bettas are agressive all the time - no matter what the community comprises of.
AND, I guess it doesnt do any good to bettas either mixing them with other fish - they mostly look stressed when with other fish.
If you are really looking for some company for your betta - the best choice would be some female bettas for him - that too two or more - though I personally have no experience of this either.
Whoa whoa whoa, thats not right at all.
First off, I don't think keeping the betta with the Gouramis is a good idea. Like spartan said, it's hit or miss.
Secondly, not ALL bettas are aggressive to all other fish. Male bettas are more aggressive to female bettas than they are to any community fish IME.
Thirdly, they do not all looked stressed when with other fish, a lot of them enjoy the extra company and don't bother the other fish at all.
And fourthly, keeping them strictly with females is not necessarily a good idea, it all depends on the attitudes and aggressiveness of the bettas, and the size of tank they are placed in.
All-in-all, it does really depend on the bettas personality. You should be able to tell within the first couple of minutes whether or not he can be kept in that tank.
Please don't say they are ALL aggressive ALL the time, because that's simply not it. And from myself, a person with this experience, don't keep males and females together unless the living conditions are appropriate.
