I would expect this fish (doing the twitching) to be a male. The other might be a male, in which case it is a display of dominance/subordination between males; or if the other is a female, it could be a display. This occurs in many species, I have seen male characins behave this way with each other and infront of a female--only last evening my Congo Tetra were doing this.
