This is true, but you are still completely missing the issue.
Fish in a store are obviously under considerable stress, especially upon first arriving. Handling that stress makes sense.
Fish in a home aquarium is a very different "kettle of fish." Salt should never be used in place of proper maintenance or suitable environment (the tank setup, filtration suited to the fish in the tank, etc) because the scientific evidence clearly shows it has detrimental impact on soft water fish [and I am still dealing with these, not livebearers, etc.].
There is absolutely no evidence from the scientific community that I have ever read that recommends using salt in a freshwater aquarium on a general, non-specific basis. As 1077 and I have pointed out, the very fact that it causes fish to produce more mucus [including in the gills] is because it irritates them; they don't like it, and that is stressful at the very least. Stress is a major cause of innumerable health problems and parasitic infestations. It makes no sense whatsoever to add stress to fish through use of salt when it is not necessary in the first place.
And as for being set in my old ways: I have been keeping fish for longer than you have been around. Nevertheless, I continually learn. Since joining this forum over a year ago, I have learned a great deal. I spend many hours a week on research. I consider the issues and see no reason not to accept the position of the vast majority when they have scientific support. That is sensible fishkeeping.
