Not all species that are piranha-like are carnivores. The Pacu-Pacu generally eat seeds that fall into the water and they look like piranhas. The Pacu-Pacu can also be kept in tropical home aquariums as a species tank.

Red belly pacus are the same thing as a black pacu and it all depends on how your pacus act.
both pacu and piranha eat live meat and they both can have red bellies too. the real difference is between their jaws, nose and teeth. piranha has a produting lower jaw while pacu has a round mouth. pacu's nose is button shaped but piranha's nose is unmistakable. and piranhas have much larger teeth than pacus.

There are several differences between the pacu and the piranha fish. One is their jaw alignment, their teeth are different. Their sizes are generally also different, a grown pacu is larger than a piranha.
