Cobalt Blue Stiphodon Goby (Stiphodon semoni)


The most colorful of all freshwater gobies in the genus Stiphodon, the Cobalt Blue Goby originates from fast moving rocky streams in West Papua, Indonesia. In the wild, it lives in small groups where individual fish stake out their own territories among the rocks. They feed on algae growth and biofilms in the wild and in the aquarium should be fed algae or vegetable based sinking foods (gel diets are ideal). They require clean, well-oxygenated water with some current and will do best at slightly cooler temperatures than most tropical fish (74-76F).
