Pacu Fish

Importance to humans
• Aquaria
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. One such example was Swish, a 75 cm (30-inch) pacu owned for over 20 years by a Chinese restaurant (Kau Kau) in the Chinatown district in Seattle, Washington; one aquarium technician said of Swish, "He'd rub his body on your arms, kind of like a dog."
