I'm going to agree with the others. Corydoras are not an option in such a small tank. I would try a Bamboo Shrimp or a Mystery Snail if you don't wish to divide.
If you would divide to get a second Betta I would so check out the buying section here. Some really great Bettas for sale as well as for rehoming.
