 It consumes a large number of benthic invertebrates, such as Chironomidaes, crustaceans, copepods, and ostracods.Gobies will also eat fish larvae; this can negatively impact the ecosystem of the rivers and lakes that tubenose gobies inhabit.In the Věstonice Reservoir (Thaya River, the basin of the Morava River) the larvae of Chironomidae, mostly "Phytotendipes gripekoveni" comprise 40.2% and "Asellus aquaticus" 27.6% as well as Corixidae, copepods, Ceratopogonidae, Cladocera, and leeches (Hirudinea).
