Battle scars, but it CAN turn into fin rot if the water quality is bad. So keep water changes up regularly and don't skip out too much.
You can conclude it's fin rot when white film starts to show up on the broken edges. That's when you start to worry. Luckily, it's easy to fix. A few water changes every few days and it'll go away on its own. :-) If that doesn't help solve the problem, start treating with meds. Though that's rather uncommon.
