Nonetheless I'd start with a water change to bring those nitrates under 20ppm.

I'll be honest. I am not sure what a salt dip is. I am pretty new to all of this. Salt has been something that I don't understand enough of so I haven't dared to try it.
Other than nitrates the weird blister things look parasitic. The way they are sparsely placed al over the body is quite bizarre which tells me it's parasitic.
Have you done a salt dip yet?
I'm missing how body placement relates solely to parasites? If you can explain more? Just curious.
1 tablespoon of salt per 5 gallons. This is best done in a quarantine tank but if you have no inverts such as snails or live plants you should be fine.
What aquarium salt does is stress the fish. By stressing them, it builds up their slime coat making them more resistant to disease. Salt should only be used in the process of medicating as long term it has shown to have health issues on the fish such as kidney problems.
