Definitely can't wait. Add more flow than needed to really have running! Oh man that's going to be bad tank. You guys think an upgrade is necessary when they hit adults? Would 1/20-25gal tank even apply to such a monster tank?
I think youre guys are a little too hung up on fish per gallon. Thats just a guideline for newer hobbyists. If an experienced hobbyist has the capability to do an epic water change schedule, than over stocked tanks become a very attainable reality. Not just for piranha, but any fish really. As far as aggression, Ive always had lower death rates in larger shoals. Not to mention you probably wouldnt notice if a few suddenly disappeared. You might get lucky and find a head with that many piranhas.
