I personally would say it is a Spotted Silver Dollar.

I have a couple of silver dollars that I purchased the other day from the lfs (because they had a minimum purchase rule for debit cards and I was only buying a little bag of first bites LOL). I know there are multiple species of silver dollars and mine are just the common ones I've seen in stores for the past couple decades. They are about the same size as pictured fish and much more round. Pictured fish however has a jaw structure that says piranha to me.

Could be a Rhom but if not, it looks like a piranha of some sort.

It's not a pacu or a silver dollar so stop saying that people!!! It's definitely some species of piranha.
