Pacu and piranha do not have similar teeth, the main difference being jaw alignment; piranha have pointed, razor-sharp teeth in a pronounced underbite, whereas pacu have squarer, straighter teeth and a less severe underbite, or a slight overbite. #aquariumhobby #reelsfacebook #aquarium | Hendrix backyard TV | Facebook

Pacu are South American freshwater fish that are related to piranha. While piranha are omnivores that eat a variety of fish, snails, insects, and plant materials, pacu are largely herbivorous. A large part of the pacu diet is made up of nuts, fruits, and seeds that fall down from the trees in their native environment in the Amazon and Orinoco River basins. At the Aquarium, we offer nuts to our pacu as a form of enrichment. | New York Aquarium
