"Record-breaking half-meter 'monster' goldfish caught in suburban Perth lake"

A biologist in Australia caught a record-breaking goldfish, measuring over 20 inches long, in a suburban lake while working to restore wetlands. The fish, likely a pet that was released into the wild, highlights the problem of invasive goldfish in urban lakes, where they disrupt ecosystems by eating plants, contributing to algal blooms, and spreading diseases to native fish. Despite the remarkable catch, the goldfish was euthanized, and experts emphasize the environmental impact of releasing pets into natural environments.
