Another suggestion for tank mates could be some smaller rasboras - harlequin for example. I have six galaxy rasboras in with my betta right now, and he doesn't bother them at all (though, they tend to stay close to the bottom of the tank, and are quite shy). I had him in a large tank (33 gallon) with guppies and platies and never had any issues - which I relate to the large tank size. I think it also depends quite a bit on your bettas personality. Just my 2 cents worth!
