What kind of Diamond Rhom?

[white_blue_grey]

Hi, I just got this new rhom 2 days ago and I want to know what kind of rhom is it?
I am pretty sure it's a Diamond rhom, but isn't there many different diamond rhom? gold, blue, etc??
Sorry about the bad quality of the picture, my camera is down so I took the picture using my cell~~
He does have a remarkable black mark besides gill plate ( just like manny) it doesn't really show in the picture tho

The elongation and shape kinda looks like a gibbus. How big is he? I could be wrong though. What do u guys think?

you got me man. Is there a collection point? The pic and age of this fish make it really hard to determine something like regional variant morphology which is always hard to determine anyway. I'd say it's a rhom. That's about all I can tell from the pic. Wait 'til it grow up some.

The thing about this is that you can pull two fish out of the same river at the same time, and one will look like the rhom for that geographic location, and one will look completely different. Not only that but piranhas in general look so completely different at various ages. That fish may look exactly like a particular"type" of rhom now (diamond, rio xingu for example), but then look like a high back black when he grows up. It's just hard to tell.
