Tail Fin Damage WHAT TO DO?!

[Dumptruck]

Hey guys, so my aros tail was a bit thrashed but it is growing back but here is a question, there is one ray that looks dead(disconnected) but not dangling, and new fins are growing around it. Do I try to pull it off? or do I just let nature take its course? and hopefully it'll fall off

Here is some pictures to show you what i am talking about.

Just let grow back and keep good water conditions.
Are you separating the fish or the culprit ?

just let it be,and keep clean water as above stated

clean water, get the fighters apart and add a slight bit of salt
