I spent the better part of the evening thinking about this fish presented to us in both the piranha photos forum and Piranha Discussion. I had my doubts in the beginning about what this fish was. As I explained in my first thread, this fish might not even be S. rhombeus, possibly S. marginatus (later revised after enhancing the image), to S. brandtii because of the placement of the anal in line with the dorsal, then considered it might be simply camera angle. Finally looking at several more photos provided which caused me to send you all to the link on unknown piranas. This fish may very well be a Xingu S. rhombeus since these variotypes seem to fit the color pattern, yet, I'm not sure. So for the sake of argument and also private PM's from the owner of the fish, I'm going to hold off completely agreeing that this fish is a S. rhombeus until better photos are made available (ie; fins grown back etc.). I will pin this topic up for now.

Here is a better photo of the Belem fish courtesy of George Fear. This one remains unknown. I presently have a single preserved specimen of it since 1993. Schleser has a live one featured in his book and according to him, Fink has not been able to determine the species:

i was referring to the same fish in the above pic..i assumed frank knew the owner since he wrote something about the owners mails and pms.
if i am wrong just say so.

thanks,

Oburi

The problem I was having with the fish photo was the condition of the fish and its fins. The pm's and emails was in reference to the person asking me to narrow it down to an exact species. Difficult to do without the fish being in front of me. Camera tends to distort colors and if the fish position is wrong, can elongate or shorten a fish body.

For the record; it is S. rhombeus (Xingu) from all appearances.
