According to fish store's list, it is Haitiensis but it looks like some Vieja species too. Can anyone find its real id?

So are you saying theLFS said its a hybrid?
I don't see haitiensus at all, but with a hybrid you can never be sure.
It does have a generic Vieja shape.
So just to compare.
Here is a young haitiensus.

and here a young Vieja melanurum

and just for grins, my first impression (if it isn't a hybrid (which is the most likely scenario)) was that it might be Maskahero's argentea.

I have raised many haitiensus over the years, and in my opinion it is not one.
I find most LFSs don't know their arse from a hole in the ground (with the exception of a few special cases), or...maybe the person they got it from, told them it was a haitiensus hoping to get more store credit, and never seeing one before, the store believed them.
Here are more haitiensus to compare.
female with fry

male with
in both cases, note the mouth and lip shape compared to your pics
