Not to the point where I thought it was a problem. I bought them when they were real small back in may, and they seemed to pair up and would do normal clownfish bickering at each other, but nothing crazy.
Okay...with clowns it's hard to say. One minute they are chummy with each other and the next they'll fight to the death. It usually takes them a couple of days for one to kill another one so you would have noticed if they were being overly aggressive with each other. Are you sure nothing else in the tank was picking on the clowns...perhaps at night while the lights were off? I ask because the dead one's tail fin sure looks shredded.
