Twospot Sandgoby

Fusigobius duospilus

The Twospot Sandgoby is a small reef-associated fish found in the Indo-West Pacific, from East Africa to the Society Islands and as far north as the Ogasawara Islands. It is characterized by a semi-translucent grey body adorned with orange-brown spots and blotches. Notably, it has two distinctive black spots on the outer part of its first dorsal fin, which help distinguish it from similar species. The species has an elongated body shape, with a rounded caudal fin and nearly fully united pelvic fins. This goby inhabits sandy floors, holes, and depressions of clear seaward reefs, often found in sand-rubble areas adjacent to reefs. It is typically observed at depths ranging from 1 to 46 meters, with most occurrences being shallower than 40 meters. The Twospot Sandgoby is a benthic fish, feeding on small invertebrates. It can be seen either alone or in groups, often exhibiting secretive behavior. Divers encountering the Twospot Sandgoby may find it shy and quick to retreat into the sand or nearby crevices. Despite its elusive nature, it is harmless to humans. According to the IUCN Red List, the Twospot Sandgoby is classified as Least Concern.
