The two moons don't move even a slight bit with respect to the main planet during the day, nor across the days. There is no obvious reason why such big moon could be tidally locked to the main planet. For its big size and proximity to the land, it should rather be moving very fast around the main planet to avoid getting dropped on the main planet.

A satellite in a synchronous orbit that is both equatorial and circular will appear to be suspended motionless above a point on the orbited planet's equator.

Centauri's nose has no nostril holes from which one can breath, so it is not made clear how he might be breathing because his lips are lightly closed so he might not be breathing from his mouth either. When other aliens were shown to have nostril holes for breathing there is no point to portray Centauri differently that raises questions that are not answered.
