The marble goby (Oxyeleotris marmorata) is a widely distributed species of sleeper goby native to fresh and brackish waters of the Mekong and Chao Praya basins. It is among the largest gobioid fish, reaching a length of 65 cm (26 in), though most do not exceed 30 cm (12 in)
How do you cook fish in a steamer?
Put at least 1 inch of water in the bottom of a steamer, cover and bring to a boil.
Lay the fish on the steamer's rack, making sure the rack is elevated above the water, and cover again. Steam 4 to 8 minutes, or until the fish is done. (A good-size halibut steak may take 10 or even 12 minutes.)
