When people no longer want their goldfish but they don't want to harm them they may release them into a local body of water. And that's creating problems!
Along an inlet near Big Woods Lake in Chaska, Minnesota, thousands of goldfish appear to be settling in. It’s unknown how the fish got there, but officials believe it’s likely from someone illegally dumping their pet goldfish. The goldfish are invasive and can create toxic algae blooms. Goldfish are also eating the food meant for the fish native to the area.
