The Blueheaded Goby, gobiidae sp., also known as the Blue Headed Goby, is a great community fish. They need a tank with plenty of live rock, a sandy substrate, and a tightly sealed lid to prevent escapes. Like other Goby species, the Blueheaded Goby will often create its own burrow in the sand - sometimes these burrows are shared in a symbiotic relationship with the Pistol Shrimp. The Blueheaded Goby has a characteristic blue head.
