Animal's Behavior 
Pacu (Colossoma macropomum) are South American freshwater fish that are related to piranha with a few big differences: pacu are vegetarians, and their teeth look startlingly like human teeth! There are several species of fish commonly referred to as pacu.

Eating Habits
Pacu eat mainly vegetation and insects, feeding on plant matter in the rivers and seeds, nuts, etc., that fall into the rivers from trees. They have powerful jaws.

Native to South America, but not uncommon in Puerto Rico and many states across the U.S.

Conservation Efforts
Pacu are not endangered. They are farmed and eaten around the world.

Animal Facts
Even though they have square, straight, molar-like teeth, pacu have a seriously strong bite. Pacu have been considered a suitable fish for home aquariums in the past; however, due to their fast growth and the size they attain, it’s now thought that they don’t make good pets.
