General: The Twin Spotted Goby (Signigobius biocellatus) naturally occupies reefs surrounding Australia, and Indonesia. The Twin Spotted Goby will reach a length of three inches, is considered to be "reef safe", and should be kept in an aquarium larger than 20 gallons. This Goby is typically a peaceful marine fish species, but may become aggressive towards others occupying the same territory. The Twin Spotted Goby may be kept with another, as long as it is of opposite gender.
The Twin Spotted 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 Twin Spotted Goby (Signigobius biocellatus) is naturally a carnivore, primarily preying upon small invertebrates such as zooplankton, and other crustaceans like mysis shrimp. It is often ideal to provide food multiple times throughout the day, especially when introducing this Goby to its new environment.
