Goldfish, as voracious eaters, will devour snails, small insects, fish eggs, and young fish, out-competing native fish. They can also grow over a foot long outside in the wild. (Pictured: A 14-inch goldfish removed by the U.S. Fish and Wildlife Service from the Niagara River that flows north from Lake Erie to Lake Ontario)

Though Cute as Pets, Goldfish Are Highly Invasive Once in the Wild

The animal’s insatiable appetites, bold behaviors and adaptability make them harmful to new environments
