Like many other bottom-dwelling gobies, the Crested Oyster Goby boasts cryptic marking and coloration designed to help conceal itself from potential predators. Typically exhibiting shades of brown coloration as its main body color, the Crested Oyster Goby sports irregular markings comprised of spots and stripes that culminate to an overall mottled appearance. Unexpected pops of bright blue, green, and maroon coloration decorates this goby to beautiful effect. This somewhat subdued coloration is pushed into overdrive during mating, transforming the Crested Oyster Goby with a spectacular arrangement of vibrant red, blue, and yellow coloration.

Naturally occurring in muddy and rocky shallows as well as oyster and mussel beds, the Crested Oyster Goby does best when housed in an established aquarium of at least 40 gallons in size aquascaped with a generous amount of live rock with plenty of loose coral rubble, ample swimming room, and a sand bottom for burrowing. The Crested Oyster Goby is peaceful but can demonstrate aggressive or territorial behavior with its own kind unless they are a mated pair. It may try to jump out of the aquarium or other small openings therefore, a tight-fitting lid is required to prevent escape.

The Oyster Goby feeds at the bottom of the aquarium, spending its day picking out morsels in and around live rock as well as sifting through the substrate for small worms and crustaceans. The Crested Oyster Goby should be offered a variety of frozen/thawed foods such as enriched brine shrimp, enriched mysis shrimp, and prepared pellet and dry foods for marine carnivores.
