it depends on the individual betta. Some are quite nice and play well with others, while mine kills anything living in his tank. Including snails. I heard him crashing into the gravel one night and found several dead ones on the gravel the next morning.
edit: I'd try with ghost shrimp first, too. They're cheaper so you're not at too much of a loss if yours end up being a killer
