A salt dip is your best bet when treating fish lice. That said, I'm not sure if the disappearing black spots are lice. How is your fish behaving? Have any more spots appeared? Are his fins clamped? Is he eating? If there are no visible spots, fuzz, ulcers, lice, etc. and he is eating, swimming, and healthy, I'd stay away from any meds. Meds are hard on a fish, and if he doesn't need them, there's no sense in putting more stress on him. But definitely keep him in the quarantine tank a while longer to make sure that whatever it was won't come back. Since the spots were black, could he have had a fungus?
