Welcome to the forum!! Your LFS is completely WRONG!
1) you are going to need to buy Marine salt, but not at the moment.
2) the fish has classic signs if Ich. That is a parasite that will Kill it eventually.
Raise the temp of the tank to 80+ degrees for 10 days. You can add salt at a ratio of 1 tablespoon per 5 gallons
3) you will need a hydrometer (later) to measure how salty the water is.
Treat the disease first then you can work your way up to brackish; raising the SG by .002 per week
Also water changes and a gravel vac are also highly recommended.
If you think I am too abrasive there is a little triangle icon in the bottom left of your screen to "report post".
