Fin rot? What can I do?

[Talisker]

Started a week ago one eye was blown out. I thought since an aggressive swimmer probably banged it into something. It's been slowly improving. Today I did notice on same side pectoral fin is blown up. I don't have a qt tank. Is there an in tank treatment I can do?

Looks to be aggression related - can you post a video in lieu of picture?

Here is a thought: the fin damage does look like tankmate aggression. It makes sense to me that this aggression would show mostly on the side of the fish with the damaged eye, because the fish "can't see it coming". Have you watched for tankmate aggression? That can be pretty difficult to see because while you are watching the fish, they are watching you and may behave differently. Also, each "hit" from a tankmate is over in a split second and one hit per day can cause this, so the chance of you actually see it happen is slim. Watch for fish making half-hearted feints towards this angel, or the angel shying away from any other fish - that may show you who the culprit is.
