The Crested Oyster Goby (Cryptocentroides gobioides) is endemic to the Coral Sea off the coast of Australia. They are naturally found in muddy shallow water they live in burrows, searching for small crustaceans to feed on. They are a brown or grey coloration with faint stripes of maroon or green spots. Their colors, while typically muted to help hide from predators, are significantly more pronounced when in mating season. They may be kept in a bonded pair, but two males would likely be aggressive towards one another and should not be housed together. They require a carnivorous diet, typically consisting of mysis shrimp or krill, and should have plenty of rock work to hide among. Their tankmates should have a similar temperament and they should be housed in an aquarium with a tight lid, as many gobies are known to jump through small openings.
