Padogobius bonelli

Padogobius bonelli, the Padanian goby, is a species of true goby from the family Gobiidae native to rivers of Croatia, Italy, Slovenia, and Switzerland preferring areas with gravel substrates or dense vegetation along the edges. Males of this species can reach a length of 8.6 centimetres (3.4 in) TL while females only reach 7.5 centimetres (3.0 in) TL. This species' specific name honours the Italian naturalist Franco Andrea Bonelli (1784-1930) who originally described this species as Gobius fluviatilis but this name was preoccupied by a species described by Pallas in 1814, the monkey goby.
