General: The Yellow Watchman Goby (Cryptocentrus cinctus) naturally sift their way through various reefs of Indonesia, the Western Pacifc, and Indian Ocean. The Yellow Watchman Goby will reach a length of three inches, is considered to be "reef safe", and should be kept in an aquarium larger than 29 gallons. The Yellow Watchman Goby is typically a peaceful marine fish species, but may become aggressive towards others occupying the same territory. This Goby may be kept with another, as long as it is of opposite gender. The Yellow Watchman Goby should not be used to "cycle" a new aquarium, and should only be placed within aquariums that already have an established culture of copepods, or amphipods.

Aquarium Diet: The Yellow Watchman Goby (Cryptocentrus cinctus) are naturally omnivorous, primarily preying upon small invertebrates such as zooplankton, bloodworm, mysis shrimp, and various algal species. It is often ideal to provide food multiple times throughout the day, especially when introducing this Goby to its new environment.
