What triggers piranha attacks?
Most piranha attacks occur when the fish are stressed, such as during breeding season when they are protecting their nests. At this time, they are aggressive and will bite anything they see as a threat. But studies show that even these bites are typically warning bites, not an attempt to kill the intruding animal.

When does a piranha sleep in the wild?
If this happens, especially if it’s dark, your Piranha are almost certainly ‘asleep’, depending on how much you are a stickler for dictionary definitions. In the wild, Piranha are meant to hunt during the day, and sleep during the night, when they are at the least risk of attacks from predators.
Why do Piranhas travel in large group of fish?
Piranhas live in groups called a shoal. It is a popular belief that these fish travel in groups so that they can overwhelm prey in a choreographed feeding frenzy. Scientists, however, think they travel together as a form of protection from predators, according to National Geographic.
What kind of piranha is black with black spots?
Pygocentrus cariba — (Cariba piranha, black spot piranha, black shoulder piranha, Orinoco piranha, black eared piranha) Pygocentrus natterei — (red-bellied piranha, red-breasted piranha, red piranha, common piranha) Pygocentrus palometa — recognized, but may be a nomen dubium (dubious name).
How big do Piranhas get when you buy them?
Piranhas can be bought fully grown or as young, often no larger than a thumbnail. It is important to keep Pygocentrus piranhas alone or in groups of four or more, not in pairs, since aggression among them is common, not allowing the weaker fish to survive, and is distributed more widely when kept in larger groups.
