Food, air, and shelter
They eat other fishes
A piranha food web shows where this fish fits into its environment in terms of food. The piranha eats other fish, so it is not at the bottom, but other animals, such as crocodiles, eat it, so it is also not at the top of the food web.
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)
There is none, generally the Red-Bellied Piranha is the "regular Piranha"
No a piranha does not have a shell!

Growth and development for a Piranha is when a Piranha gets horny and breeds/mates with another Piranha and they blow up out of nowhere?
