I don't know why the purple anomie moved down and now these two are going at it why and how do I separate them please help asap

Maybe aim a powerhead at them? I read a post where someone suggested freezing a bottle of water and holding it near the nems not sure if it is a good idea or not. Maybe someone else can answer that for us
