I would get at least a couple more Otos before anything else. Cory Cats are also awesome fish with Bettas. My boy loves his five Cory friends, and follows them around sometimes when they search through the gravel. Though Cories need to be in groups as well, just like Otos do. They can get very stressed out if they don't have a group. They need to live in groups for security and to feel safe. And their behavior is much more interesting to watch when they're in groups. Though having both Otos and Cories would definitely Overstock your tank. But the Oto should definitely have some same species companions.
