Make sure that you have a backup tank in place in case they need to be separated.
For what it's worth, I have a shoal of pygmy cories (collectively called "The Itty Bitty Fishy Committee") that have shared their tank with my bettas throughout the years.
Out of all bettas I've had, only one tried to murder my cories and so he was rapidly transferred into his own tank. The rest of my bettas either ignored them or hung out with them. :)
