Your fish is indeed a parrot pacu, Ossubtus xinguensis. Very interesting and beautiful Serrasalmid fish, in what is considered a monospecific genus.
The fish that is the subject of this thread IS a Metynnis, a genus currently including 14 species.
I am now uncertain whether Wes was stating that it is not a Metynnis. Hopefully that is not the case.
The issue as I understand it is whether it is a variant of Metynnis fasciatus, or a different species in the same genus. I am inclined to think it is a variant of fasciatus, but I have not seen it before, and don’t know more than Wes or have seen more than the pictures shown in this thread.
