Most species are opportunistic predators. They will eat nearly anything from plant life to other fish, insects, carrion, worms, and so on. Some species are adept at scale-eating and feed primarily by nipping off the scales or fins of other fish. This is more common with juvenile fish and smaller species. Piranhas also scavenge quite often.
The breeding habits of most species are relatively unknown. Most known breeding behavior has been observed in aquariums. These fish can usually breed by the time they are a year old. Females lay thousands of eggs near thick vegetation, to which the eggs stick. Males fertilize the eggs, and then the eggs hatch after two or three days. Young fish wil...

The piranha will often quickly swipe the bait before i...
