An Oscar is of the cichlid family, the piranha belongs to the characin branch. Otherwise known to freshwater aquarium owners as the bothersome "fin-nippers" which is what characins are known for, along with the skittish hyper behavior.
Piranhas are in the subfamily Serrasalminae. Other fish that are in this subfamily and that are closely related to the Piranha are Pacu and the Silver Dollar
They are related
yeah... kinda
Oscars and piranha think they are delicious and swordtails and mollies pick on them sometimes. Anything that eats feeders will eat guppies
No. Oscars are in the Cichlid family that contains others species like JacK Depseys and Angelfish. Piranah are Characins and that group contains species like Neon Tetras and Silver Dollars etc..
A pacu is any of several South American freshwater fishes related to the piranha.
Silver Dollar's are in the Characidae family which are closely related to Pacu, and Piranha. Silver Dollars should be kept in schools (3 or more), and in larger tanks due to their size.
There have been five movies with piranha in the title: Piranha (1972), Piranha (1978), Piranha Part Two: The Spawning (1981), Piranha (1995) TV, and Piranha (2010)

Oscars are tough buggers and get pretty big the only thing that could kill a full grown Oscar is age or you. If you want to get rid of it which hopefully this is not why you asked the question just call a small chain or family owned pet store they will usually take it.
If your tank is at least 8 foot long by 2 foot high by 2 foot deep you may get away with a couple of each.
No. Other than their accidental or deliberate release by humans, piranha are found only in South America. There is also a related indigenous species called the pacu.
