My 2 Ocellaris clowns, who have been together in the tank for almost 5 years, suddenly began attacking each other a few weeks ago. They’re both about the same size, one just a tiny bit bigger, but they are going at it. I was concerned at first because it seemed to be extremely violent, like a fight to the death. However, after a few weeks, I see that there are no fins torn, no eyes gouged, and no other apparent physical damage. They’re not even really hitting each other. It just seems that way. So I guess it’s a mating ritual to determine who gets to be the female. Very strange.
