I have to diagree about a betta not being able to be with other fish as I have a very happy non aggressive betta in my 55g with tetras, loaches, a snail and others. There are many suitable fishies for a betta tank.Lauren said:I struggled finding any swimming fish mates for a betta in a 10 gallon, I finally gave up, moved him to a 5 gallon, and focused on a tetra community tank. I've heard that white clouds might work? I don't know, betas pretty much have a gurdge against anything that swims.
