Comet Goldfish - Not sure what's wrong

[freeezerburn@hotmail.com]

The comet goldfish in my pond was not swimming around like the other fish in my pond (From Eastern Pa, we had a pretty rough winter).  It was hanging out in the bottom of the shallows and pretty limp.  I moved him to a quarantine tank in my garage and slowly began warming up the water and added some aquarium salt.  Seems to have a wart-like growth near the gills and a bit of fin rot.  Any ideas on what is wrong / how to treat.  I don't think it is ich, but I could be wrong.
