I've had two pairs of clownfish in the same 120 gallon tank for over a year now. When I came home from school this weekend, I noticed that one of the pairs fins were ripped up. The smallest one in particular was a lot more ripped up. I know it was definitely the other two clownfish since I've seen them chase the other two a little bit since I noticed their fins. Not sure if I should take them both back to the fish store or see if there's another way to fix the aggression, especially since there have been no issues till now.
Any ideas or suggestions?
