i want to make sure that i know how to tell a black piranha apart from other species. the black piranha has a pointed head? so would this be a black piranha? how do you tell the difference between black piranhas & other species?
That is S. rhombeus commonly called a black pirana. But also many others are known by that common name. Majority of piranas when young have that pointed snout. Later morphing into distinctive head shapes.
