Piranha is a kind of piranha. Carnivorous and man-eating pomfret, whose real name is nattereri, is a sawtooth carp in the north. This fish is 30 cm long (excluding the tail fin). Man-eating pomfrets are mainly distributed in rivers in the Brazilian plain east of the Andes. Besides Amazon River, Cuyaba River and Orinoco River are also its main producing areas.
Piranhas inhabit the main stream and larger tributaries, where the river is wide and the water is urgent. Adult fish mainly feed at dawn and dusk, mainly insects, worms and fish, but some related species only eat fruits and seeds. The activities are mainly during the day, and will rest in a sheltered place at noon.
"Piranha" is not strict with water quality, and likes weak acidic soft water. The water temperature suitable for growth is 22 to 28 degrees Celsius. This kind of fish feeds in groups, and the staple food is relatively small fish. They hunt anything that moves in the water and are particularly sensitive to the smell of blood. Any smell of blood will arouse a large group of "piranhas" to attack fiercely. Piranha is strong and easy to raise, but it can't be raised with other fish.
