Why ‘Monster’ Goldfish Appearing in Lakes Are Bad for the Environment

Some kids in Maple Grove, Minnesota recently caught an enormous goldfish in the lake outside their home. ‘Monster’ goldfish are turning up in many freshwater lakes across the US. The big fish are former pets. When people dispose of them, they often end up in the wild, where they can wreak havoc on ecosystems. Experts say if you need to get rid of your goldfish, give it to a friend or return it to the pet store.
