MAYBE. I have many times kept bettas with corys, most recently I have a shoal of corys in a 10g with a male betta. The corys have to go because they have outgrown their home, but they get along fine with the betta, save for the cory eggs the betta eats. BUT... I understand that pygmy corys tend to be more active. This maybe an isolated incident, or it might be a trait that will lead the betta to get angry. If you do attempt such a coupling, I would have a second home for the betta or the corys ready should it be necessary.
