1. Their nicknames are different

The red-bellied piranha is also known as red-bellied piranha, red-bellied piranha, and piranha. Its scientific name is Nassian piranha.

The black-spotted piranha is also known as black food and black violet piranha.

2. Different distribution areas

The red-bellied piranha is distributed in areas with gentle water flow in the Amazon Basin of South America and surrounding shallow ponds and lakes. The output is huge because of its reputation as a "piranha" It is popular all over the world and is one of the most famous fish. It is a famous sport fish and edible fish in its place of origin, and it can also be used as an ornamental fish.

The black-spotted piranha is distributed in South America, in the Amazon Basin, Orinoco River Basin, Guyana, Venezuela, and Peru.

3. Different habits

The red-bellied piranha has thick and powerful jaws, and each of the upper and lower rows of teeth is in the shape of a dagger, sharp and protruding.

The black-spotted piranha is as strong as an ox, with strong adaptability and super recovery ability.

The red-bellied piranha has a pair of blood-red eyes, creating a blood-sucking devil-like aura, which is unique among the genus Piranha. The conditions for raising them are relatively simple. The water quality is slightly acidic and the water temperature is 25°C~30°C. It is worth noting the following points:

1. Piranhas will become more manic in high temperatures. If the temperature exceeds 30°C, they will bite other animals, including their own kind, so they need to be controlled. .

Two, try not to feed food that is bleeding or live chickens and ducks, as such things will drive them crazy. The sign of madness is that they will eat desperately and even jump out of the tank.

3. Don’t feed too much food. The reason why piranhas eat fiercely and have sharp teeth is the result of evolution. Fishes of the order Cyprinidae do not have expandable lips and cannot swallow large prey. If they want to eat meat, they must grow sharp teeth to cut it off. In other words, if the prey that is fed is too large, a pile of meat residue will be bitten out of the water, which can easily corrupt the water quality and lead to the death of the fish. Just use ordinary small miscellaneous fish.

4. Piranhas are relatively short-mouthed. A set of fangs is not a decoration, and it cannot be idle when not eating. Piranhas that have been idle for too long will always bite here and there to vent their energy. But their teeth are so powerful that they can easily bite through the wires of the heating rod, causing them to be electrocuted.

So in order to avoid the tragedy of "being struck by lightning", you must make a grille for all the wires in the tank in advance so that the piranhas cannot eat.
