A Piranha ID, please...

[mulea]

Two days ago I've bought this Piranha. Now... I may take a guess what it can be but I'd like to hear it from the PROs.
Could you help me identifying this fish, please?

THANK YOU!

s. Sanchezi, and a very nice looking one.

I have to take back what I said and agree with S. Sanchezi!
Definately NOT irritans..

Thank you all, my friends!
I'm so proud having such a Piranha home!!!
By the way - could someone tell me what's the minimum tank size for this guy and if it needs a strong water stream or a medium one, please?

A HUUUUUUUGE THANK YOU!
