The Soft Coral Goby (Pleurosicya boldinghi) is a small fish (it reaches a length of around 3.5 cm) that is known from Japan, New Guinea, Indonesia, and the Great Barrier Reef in Australia from depth of around 20 to 127 m. This species is commensal with soft corals of the genus Dendronephthya (commensal organisms benefit from their association with a host, but there is no associated cost to the host, as there is in the case of parasitism). Randall et al. (1996) provide a technical morphological description of this species.
