Definitely looks like a parasitic infection by the way the fish are carrying themselves (clamped) and other obvious stuff.
I'd really jack the salt up and run a UV for a couple of weeks. A giant water change to start would be nice (eliminates a lot of the free floating stages of the parasites). Then I'd change 50% every other day (adding back salt to cover the new 50% of water). Keep salting, etc. at least a full week after they look clean.
