Jack Dempsey cichlids are aggressive aquarium fish named after the heavyweight boxer Jack Dempsey. They are native to Central America but were discovered in a flooded quarry in New South Wales (NSW) Australia in 2004. Although efforts were made to eradicate them in 2004 and 2005, the fish remain. Jack Dempsey cichlids are one of about 30 aquarium fish species that have become established in Australian waterways, and have been shown to have a significant impact on Australian aquatic ecosystems. They highlight the importance of preventing the importation of invasive fish species because they are extremely difficult or impossible to eradicate once they become established in the wild.
