Exotic Pet Found in Lake

Type: Nontidal
Region: Central
Location: Buddy Attic Lake

I caught this in Greenbelt, MD at Buddy Attic Lake on 7/10/15, I think it's an Oscar, did not put back, gave to another fishermen, he going to eat it.

DNR Response: Yes, the fish appears to be a tiger oscar which is a member of the cichlid family and comes from South America. Thank you for not putting it back in the water. It seems that someone must of dumped their pet in the lake. Releasing exotic species into the environment is illegal and irresponsible.
