Yesterday my wife noticed our two clown fish fighting with each other early in the morning yesterday and again they went at it this morning. During the day they are always next to each other with the slightly bigger one occasionally bumping the smaller one but from what I am read it seems like its normal as the bigger one takes the dominant role. She caught some of it on the video below and neither was hurt yet. I just want to make sure I shouldn't be worried or should I take the bigger one out. Both are small clownfish, tank size is 120g with 100 lbs of live rock so plenty of hiding spots.
