I would recommend 1 male betta, or 3 female bettas and some ottos or shrimp. Do not combine bettas and snails if you can avoid it. Snails require calcium supplements and hard water, and bettas prefer soft water.
Orange platies is also a good idea, very active and pretty fish. Or how about guppies? They come in beautiful, vivid colors, and if you get only males you can have a fairly large group of gorgeous little guys in your small tank.
