Now I'm trying to visualize the orbital dynamics.
Are they tidally locked in respect to each other, so that each world only ever sees one face of the other?
If so, there's going to be one face of each world that never has a moon in the night sky. Species exclusive to that side might well have decent night-vision.
If not, then no place on either world will always have a "moon" visible at night.
