Well, I did a risky experiment over the holidays! I bought 2 Betta pugnax and put them into my 30 gallon aquarium that has a single male pearl gourami. So far they have not bothered fighting each other. The Betta pugnax fishes, however, are more gluttonous than my male pearl gourami. In my experience, I've had pearl gouramis be more aggressive to their own species than to other anabantoids in the same aquarium.

Nuuuuupe. Gourami will bully the hell out of them. Gourami are quite aggressive and should not be with betta’s at all and if the betta gets in the way it’ll have to fight it out. Idealy you separate them ASAP.
How young are the bettas? I’d keep an eye out for more territorial behavior as they mature
