I have no idea what to advise to treat a perfectly healthy fish. Perhaps a nice dose of water change and fresh food.
Salt is for breeding brine shrimp and treating ich, otherwise leave it on the shelf. Medications are for when there is something wrong. Does your healthy looking molly have something wrong?
