Heya 
I was wondering how bad this fin rot is:

and treating it with aquarium salt is enough?
I thought a picture might help as i have not had fish/fin rot before and want to know as i will buy something extra (Kanaplex) if needed. I just can't judge it myself. There are a few pin holes, black around the edges and parts look like they will break off (very fragile) especially on his dorsal fin and beard.
