Fin damage. What to do?

[kilnakorr]

I noticed one of my discus have gotten a damage tail fin. My question is if the fish will be fine with this damage (if it will heal properly and so on).

Really hard to tell what's in that pic but doesn't look good. Looks deep and pretty bad

I don't like the look of it either. I'll try to get a better pic.

Picture not good. Show the entire fish, please.
