Fish with teeth are never good news.

The Department of Natural Resources is confirming that a local woman caught a Pacu fish in Lake St. Clair last Wednesday. The fish is native South America, and measured at about 14'' long.

The DNR thinks it was most likely a pet fish that someone set free. The fish have square teeth, almost human-like, and can grow to about 55 lbs, which is much larger than their piranha relatives.

Pacu are commonly sold as "Vegetarian Piranhas" to home aquarium owners. With the proper equipment and commitment, pacu have been known to make responsive pets.
