The Two Spot Goby has a number of different names. It can also be referred to as the Twinspot Goby or Crabeye Goby. You should keep them in atleast a 10 gallon or larger aquarium with live sand as a substrate for them to burrow/dig in. They rarely act aggressively towards other fish, but they are territorial, and will fight with own kind unless they are a mated pair. If conditions are at a good constant, the Two Spot Goby will spawn successfully in an aquarium. The Two Spot Goby feeds off the bottom sifting through the substrate for food. They should be fed a variety of either live or frozen brine shrimp, mysis shrimp, or live black worms.
