PASSAIC - A North Jersey man got quite a surprise while fishing over the weekend when he pulled out a 10-inch fish that's a cousin to the piranha.

Tom Boylan says the fish, called a pacu, was caught in a small pond in Passaic on Saturday.

Boylan fishes every day, and normally only catches carp and catfish.

The pacu he caught is normally only found in the warm waters of the Amazon.

Boylan says he was shocked at what was on the end of his hook. "I suspect someone emptied their fish tank into the pond and that's how the fish managed to get there," he says.

Pacus are a less dangerous cousin of the piranha and have rounded teeth. They can grow to be larger than piranhas, up to about 40 pounds.
