More Corys would be best as they are a schooling species. The more of them there are, the more comfortable and secure they feel. Do you have live plants? If not, you will need to do a 30% weekly pwc with the added bioload just to be safe. You can add the snail if you are willing to do any extra water change.
I divide my pwc instead of doing it all at once. Easier on me and less stressful on the fish IMO.
I have a 10gal with my Betta and Mystery Snails. I will be adding Corys later. From what I've read, Mystery Snails have a bit less bioload than Nerite and unlike most snails, Mystery Snails are sexed, so unless you have both a boy and a girl, no babies!
