there has not been enough (read: ANY) genetic studies to even confirm whether hybridization between these species (or any pygocentrus species) is possible.
there are red bellies that develop slight humeral spots like caribes but these are still not hybrids the givaway is still the shape of the head (less bulldog like than most caribes) and the colour of the eyes (red, cariba's eyes are always clear)
i never really lookind into this untill i saw the thread i jus went with what my lfs told me.. anyway what iv found the last couple days is agreeing with you guys. from what iv found the only consistently bred piranha in captivity are nattereri and thats that. but whilst were on the subject can anyone shed some light on the ternezi for me?
