To soften the blow to children, and to rid themselves of unwanted pets, Mom and Dad tell kids lies like, "Your goldfish just went to live on a farm in Colorado." Except in this case, it really happened -- and then the fish got revenge in a Hitchcock-ian way and overtook the lake.
Thousands of aquarium fish have recently been found swimming around a lake in Boulder’s Teller Park, and it's a big problem. Park officials believe someone illegally dumped goldfish in the lake a few years ago, and since then, they've reproduced like rabbits. Or like free-range goldfish. Either way, the lake's now teeming with ring-toss prizes.
And though the goldfish may seem cute, they're actually destructive; the exotic, store-bought fish can be harmful to the other fish and upset the lake's entire ecosystem.
"Most people don't realize the far-reaching effects of introducing exotic species to the environment," Ken Kehmeier, Colorado Parks and Wildlife’s senior aquatic biologist, said in a press release. "Non-native species can be devastating to native populations by causing disease outbreaks and creating competition unbalance. It's an issue that anyone concerned with our environment should know about."
