They do seem to have similar body shapes but when I looked up the geryi a few websites said things like:
"Geryi's Piranha has a brighly shining silver colored body. The coloration turns darker towards the upper body. The most striking feature of this very pretty species is the violet to purple line running from the base of the dorsal fin to the tip of the upper jaw." http://www.piranha-info.com/default.php?lang=en&id=s_geryi
But as you can see from my pictures my Spilo has the red throat Spilos are known for
"Sanchez', or Ruby-Red Piranha owes its name to the bright deep red belly once mature. The flanks are speckled with iridesecent silver scales. The body is compressed, and rhomboid in shape. The shape of the head is concave." http://www.piranha-info.com/default.php?lang=en&id=s_sanchezi
The main reason I know its a Purple Spilo is because I bought it from Aquascape and I trust them as do a lot of members on sites I'm on.
