The only reason anybody could suggest it was parachromis might be because of its pale face (Bridge area between eyes)... aside from that, the pattern and body shape does not deviate from a cuban at all. (Obviously the shape is different from a young animal though, but yours is an average adult).
Here is my recently acquired 8.5" Cuban: (see how it also has that slightly pale region? Yours is just a tad bit more pale, thats the only difference, otherwise, absolutely cuban).
