Glossogobius giuris
Tank Goby (also Flathead Goby)
One of Australia and New Guinea’s largest and most taxonomically active goby genera, Glossogobius (“Flathead Gobies” or “Tank Gobies”) includes some of the region’s largest and most commonly encountered freshwater gobies, several only formally described within the last two decades.
One of the family’s largest members, Glossogobius giuris reaches up to 35 cm and has an exceptionally wide distribution, from the Fortescue River in Western Australia to the Fitzroy River in Queensland, throughout New Guinea, and across the Indo-Pacific from East Africa. It is markedly euryhaline, found from marine coastal habitats to inland freshwater reaches, including fast-flowing torrents in the New Guinea highlands, tolerating water temperatures of 23–38 °C, dissolved oxygen down to 5.4 mg/L and pH 5.6–8.3.
