No I wasn't saying they would nip the betta hon, just them swimming fast can stress the betta out.
Habrosus is the biggest of the pygmy corys. There is habrosus, hastatus, and pygmaeus.
So, as nc said, pygmies are better since they are smaller Just depends on what you can get a hold of.
I personally am getting habrosus because I've heard they don't swim up in the mid to top level of the water as much as pygmies, but I'm putting mine in a 20g long, with my betta Discord.
