Piranha II: The Spawning is one movie that is quite special and unique, not so much because of the generally “deadpan” script and cinematic factors of the movie, but more because it was actually directed by James Cameron of The Terminator and Avatar fame.
Though Cameron did eventually get to direct and pen down better movies after, the film, as a creature-feature, showcased mutated piranhas which gained the ability to fly through “fin flapping”, which generally caused a lot of problems in and out of the water for the movie’s cast characters.
No, they can’t.
In fact, piranhas have been victims of unreservedly being pegged as rabid fishes, as mindless bodies of teeth with eating out anything being their only priority.
Piranhas are actually kept by many as pets, housed in aquariums in different households where keeping them as pets is legal. As pet fishes though, they are not like your average goldfish, and their care and keep also has a degree of danger and risk involved.
As fish types, there are different piranha species and as a species they are classified as omnivores, since there are certain piranhas which only eat plants. Bet you didn’t know about that.
Also, as pet fishes, piranhas tend to grow to large sizes, with some measuring as big as two feet. Large tanks/aquariums are really necessary if one intends or keeps a piranha. Also, piranhas are generally kept in small numbers, at times even as solitary fishes. This is because there are cases of piranhas attacking their fellows in same-shared tanks.
But with its particular upkeeps and care aside, piranhas are interesting pet fish to have, though care in their handling has to be constantly maintained, ensuring that no harm comes to piranhas and pet owners, alike.
