I fed my angels a cube of bloodworms this morning. During the feeding everything was fine. Once they were finished, the lip locked 2 times and just kept darting at each other with some twitches here and there. Now they act like nothing happened and swim around the tank with the occasional nip. Did I experiance aggressiveness or pre-mating thing???? It was really cool to watch during the lip-lock. They both turned completely sideways befor letting go!! It was really cool!! Can anyone shed a little light?? Thanks!
