Why is he hitting a jig?

I see him arch and lift his butt sometimes when the lid is closed and I look at him. I think he gets triggered by shadows through my curtain in the distance if not my own shadow. In this one he's wiggling his butt with the lid open. He's solitary, his roommate on the other side of the tank isolated from meeting because he's a bully. Just in case, is this potentially a bad jig?
