Two Black Piranhas

Hello, I have a 125 gallon aquarium, and I was wondering if I would be able to get two black piranhas from babies and raise them to adults and switching their tank to a bigger tank when older without them being aggressive towards each other or trying to kill one another? or is it just impossible to do in a home aquarium do to the nature of the black piranha? If you have any information you believe I should know, please do.
