Twitchy, grumpy oscars, what's the cause of this behavior?

[HenryC]

My 2 albinos sometimes do this behavior where one becomes kind of grumpy and pushes sand around, opening his mouth wide and shoveling the sand, and they both twitch like in the video. Sometimes they will open their mouths very big like going 😮 and then appear to have a confrontation?

Is this breedinh behavior? Or maybe marking territory? They never fight or lock lips but they surely look grumpy.

Looks like breeding behavior to me.
