The monkey goby originating from the Ponto-Caspian area, has appeared in increasingly wide-spread areas of Hungary. In the Tisza-to water reservoir in North-Eastern Hungary along the Tisza River, 83 first summer samples of the fish were collected in the vicinity of Tiszafured on October 21st, 2000. The average length of the fish, not including the caudal fins, was 50,4 mm, the average weight was 2.1 g. Their alimentari canals contained mostly gnats (Chironomidae), but also the relative amount of the taxons Copepoda, Ephemeroptera, Ostracoda and Odonata was notable.
