There are a number of aquatic species that have gone feral after introduction into the wild by aquarists, anglers and even by the government.
Not only can these species outcompete natives, and predate on them, they can also spread nasty diseases that can affect our primary industries.
In this day and age, we should know better. Heed the advice of, “Don’t dump that fish!”
“Crocodiles might not be the only predator to worry about when you take the tinny out in the Top End.
The brightly coloured Siamese fighting fish, or betta, has gone rogue in the Adelaide River and floodplains near Darwin..
Breeding by the thousands, the fish have reverted back to their most natural territorial form, losing their bright ornamental fins and instead flaunting brown camouflage scales.”
