It should reside in a 10 gallon or larger aquarium with live sand as a substrate, and an attached populated refugium. It will rarely act aggressively towards other fish, but is territorial, and will fight with its own kind unless they are a mated pair.
Under correct conditions, the Two Spot Goby will spawn successfully in an aquarium.
Usually the Two Spot Goby feeds off the bottom sifting through the sand for food. It should be fed a variety of either live or vitamin-enriched frozen brine shrimp, mysis shrimp, live black worms, and prepared foods for carnivores.
