i am not sure if one on one ratio (piranha vs oscar)could have
a chance, but i won't do that. i come to understand that solitary
piranha become less aggressive and won't attack any other fish.
however, if you have school of piranha......goodby oscar.

as to feeding with tuna.... as long as it fresh or fresh frozen,
that would be fine.... but if it is in can... stop...it is not good.

i never feed my chickens, chicken.... i dont think it would be right.

im not sure about tuna to a fish... but they do eat fish dont they.

what oil/water is it canned in?

Ok everyone else answered your questions but I have to tell you, One Oscar in a 55 is all you should have... No tank mates. Oscars need space and I wouldn't recommended putting anything else in the tank.
