The research published in NeoBiota showed goldfish to be voracious, consuming much more than the white cloud mountain minnow or native species. In terms of behaviour patterns, goldfish were also found to be much braver, a trait linked with invasive spread

Invasive species are one of the leading causes of global biodiversity loss, and the pet trade is responsible for a third of all aquatic invasive species.
Pet owners releasing unwanted pets into the wild is a major problem. Whilst many believe this is a humane option, new research suggests that attempting to `save` the life of a goldfish could in fact lead to catastrophic outcomes for native biodiversity.
