Speckled mosquitofish – Phalloceros caudimaculatus

Speckled mosquitofish are brightly coloured, hardy and relatively easy to breed. As a result, they are a popular aquarium fish and have been transported around the world by the aquarium trade.

Speckled mosquitofish were recently discovered in a NSW waterway. This raises concerns about the potential impacts of yet another introduced freshwater fish in NSW. Detrimental interactions with introduced pests are considered a major threat to native aquatic biodiversity, and the ‘Introduction of fish to freshwaters within a river catchment outside their natural range’ is listed as a key threatening process under the NSW Fisheries Management Act 1994.

It is usually extremely difficult to eliminate pest fish once they have become established in the wild. It is therefore vital to prevent noxious pests such as speckled mosquitofish from entering or spreading further in our waterways.
