Piranhas as a pet

Piranhas are not as aggressive fish as people think. However, within the different types there are some more dangerous ones. One of them is the red-bellied piranha. This type of piranha has neurotransmitters in its brain that make it attack the first thing it sees when it is hungry. However, when it has food and water, it poses no threat to humans.

The colors of piranhas are very varied, including red, yellow, silver or orange. In addition, as they age, the shades fade and darken.

Regarding their morphology, aquarium piranhas have a large head with a robust skull. Males are usually indistinguishable from females, although the latter have a smaller skull and change color when laying eggs.
