From pet to pest, goldfish can wreck entire ecosystems

Goldfish, once just charming pets, have been shown to cause significant ecological disruption in the wild. A recent study highlights how these seemingly harmless fish can cloud water, disrupt food webs, and harm native species, leading to major ecological changes. This discovery underscores the importance of considering the environmental impacts of even commonly introduced species, emphasizing the need for more responsible pet ownership and management of invasive species to protect natural ecosystems.
