The Black-Barred Reef Goby (Priolepis nocturnus) has many common names, including the White Tiger Goby, Circus Goby and Convict Goby. They can be found among reefs in the Indo-Pacific, where they hide in coral and crevices. The body is a pale white with brown or gold vertical stripes, as well as orange stripes originating from their eyes. They are peaceful fish that do well in nano reef tanks. They should be kept with other peaceful community fish and should not be housed with precatory or aggressive tankmates. They do best either by themselves or in a pair, but should not be kept in large groups of the same species, and do well in established tanks with high populations of copepods.
