It can be found in Austria, Bulgaria, Croatia, Czech Republic, Germany, Hungary, Italy, Romania, Serbia and Montenegro, Slovakia, Slovenia and Ukraine. ==Description== The Danube gudgeon grows to a maximum length of , though a more normal size is . It has a distinctive pair of barbels at the corner of the mouth which are long enough to extend back to beyond the eyes. These are tactile organs and are used to search through sediment for edible items.〔 There are no scales on the throat and this helps distinguish it from its close relative, Kessler's gudgeon ''(Romanogobio kessleri)''. The dorsal fin has seven branched rays and the general colour is silver with a few dark spots. There is a thin blue streak that runs along the lateral line.
