SCHENECTADY, N.Y. (NEWS10) – An elusive, warm water fish that’s been swimming in a Schenectady lake has finally been captured.

Local fisherman, George Marx, caught the alligator gar Friday afternoon.

The fish has been swimming in Iroquois Lake in Schenectady’s Central Park. It was first found by a lifeguard who tossed it back into the lake.

The alligator gar, however, is considered an invasive fish, so the New York State Department of Environmental Conservation asked people to find it. Mayor Gary McCarthy also issued a $100 reward for the person who caught the fish.

The DEC said the alligator gar can grow up to 14 feet long and was likely someone’s pet that outgrew its aquarium.

NEWS10 ABC left a message with Schenectady city officials but has not heard back.
