I always add a bit of Salt in my Goldfish aquariums.
I wonder if Oscars like a bit of Salt in their water?
If so what concentration?

Salt in an Oscar aquarium is irrelevant, unless there's enough in the
tank to do damage. I wouldn't bother with thinking about it or go
through the effort of trying it.

However, ironically enough, Baron de Cuvier, the individual who first
"catalogued" Oscars, thought they were salt-water fish; he discovered
them (quoting him) "at ocean off Brazil".
