What happens in this video?

[nötter]

Two females fights? Or could it be a spawning? which suggests my bichirs when he eats something in a cave.

It looks like fighting to me. My Syno Granulosa move their mouth like that when acting aggresively toward one another. The movements also match when my Grandiops fight. I would surmise that the bichir is attracted to the action in anticipation of a potential meal.
