A controlled study comparing six native fish species with the introduced (and invasive) eastern mosquitofish (Gambusia holbrooki) on consuming larvae of the common banded mosquito (Culex annulirostris) in Brisbane found that the empire gudgeon was as efficient at eating mosquito larvae as the eastern mosquitofish and is a good candidate for ...
The Danube gudgeon grows to a maximum length of 15 centimetres (5.9 in), though a more normal size is 10 to 12 centimetres (3.9 to 4.7 in).

These are tactile organs and are used to search through sediment for edible items. [3]
