Studies have shown that this marine goby is native to the Indian Ocean and the western Pacific. Midget dwarfgoby was described in 1981 from the Chagos Archipelago, the center of the Indian Ocean. Distinctive features of this species are having a semi-transparent body and slightly orange-colored. This species has a standard length of 8-10 mm in adult females. The midget dwarfgoby inhabits mostly in deep coral reefs at depths of 5-35 m. This fish species is considered in the IUCN Read List as a species with Least Concern (LC). M3 ER -
