Description
The Eastern Tubenose Goby is a small, bottom-dwelling fish characterized by its distinctive tubular nostrils. Native to the Ponto-Caspian region, it has become an invasive species in many freshwater systems, including the North American Great Lakes. These gobies are generally hardy and can be territorial, especially during breeding.
