The most commonly traded brachygobius species is doriae like the op's fish and the most commonly traded true freshwater species is aggregatus, which is easily distinguishedBumble Bee Goby. To my knowledge there's two kinds, one fully fresh water and one brackish water one. I do not know how to tell the difference sorry! Cute little guy though!

May I ask what are it's tank mates?
The goby is a slow eater and often times difficult to feed. My tank is a 20 gal long. I have one side of the tank with a very fast current, and a low current on the other side.
They like to "catch" their food in the current. I have never seen mine eat off the bottom. I take frozen foods like blood worms and slice it very thin, then I drop it in the fast current.
I also have a balloon Mollie in with them to help keep the foods that have fallen to the bottom eaten. Since the Mollie is a slow swimmer, my gobys get plenty to eat.
I also keep mine at a specific gravity of 1.004 and 1.005, using marine salt not aquarium salt.
I hope this helps
