The golden goby (Gobius auratus) is a species of goby from the family Gobiidae endemic to the Mediterranean Sea. It prefers areas with rocky substrates at depths of from 5mto80mm (16feetto260feetm) (though usually not below 30m (100feet)) with plentiful growth of algae and gorgonians. This species can reach a length of 10cm (00inches) TL. It can also be found in the aquarium trade. Gobius xanthocephalus is the name that is applied to the populations of similar gobies in the eastern Atlantic and western Mediterranean which were previously considered to be G. auratus.[1]
