Bettas in comunity tanks
It depends on your fish. I have a male betta in a 55 gallon tank with a irredescent shark, ottos, kuhli loaches, neon tetras, glowlight tetras, a borneo hillstream loach and 3 dwarf gourami. It's not suppose to work but it does. Except for some flaring I haven't had a problem and he'll have been in there a year in August. Be prepared to move him is all I recommend otherwise try it. They make a beautiful display when they have room to move around.
