No guarantees with Bettas. Just because a particular fish worked for someone else doesn't mean it will work with you.
Depends on the Betta's individual temperament, but it also depends on various factors of the tank itself, such as tank size and plant density\ or areas that keep fish out of lines of site.
Like it was recommended, if you do decide to try other fish with your Betta, just make sure you have another tank to separate them if need be.
