Do the Banu breathe other atmospheres besides oxygen?

Not specific gases yet, but overall we've talked about how their survivability is much higher than humans. They can exist in a much broader range of environments.

I can't remember the name of the specific system, but if you go on the star map, there's actually a system that has arcologies where basically the atmosphere is lethal to humans, but not to them. But they still want humans to come visit, so they've built these arcologies so you can hang out inside while they hang out outside.

Enjoy the beautiful Banu vacation world. And wave at you.
