A boy caught the toothy fish in a Labor Day fishing derby at Kiwanis Lake in York. York parks supervisor A.J. Grimm says it's been frozen so the state Fish and Boat Commission can examine it.
He says several people who have looked at the fish say it is probably a pacu fish. A pacu is a freshwater tropical fish with rounded teeth that grind plants.
Grimm says it probably ended up in the lake because someone dumped their aquarium. He says officials are trying to find out where the fish came from because pacu also could harm plants and wildlife in the lake.
