Hector’s Goby is found in the Indian Ocean, including the Red Sea, and as far as Micronesia in the western Pacific Ocean.
It lives in protected coral reefs at depths of 3 to 30 meters (usually 5 to 20 meters). This fish is found in the aquarium trade and is safe for reef aquariums.
The name “Hector’s Goby” honors Gordon Hector, who was once Chief Secretary of Seychelles’ government and helped with Smith’s research there.
Hector’s Gobies prefer sheltered bays and inner reefs with fine rubble shaded by large living corals.
They are usually seen alone, floating just above the sandy bottoms of reef bases. Their diet consists of filamentous algae, copepods, ostracods, amphipods, and nematodes.

Hector’s Goby Physical Characteristics
Size: 3.3 inches (8.5 centimeters)
Hector’s Goby grows up to 3.3 inches (8.5 centimeters) long. It has 7 dorsal spines, 15 to 17 dorsal soft rays, 1 anal spine, and 15 to 16 anal soft rays.
Key features of Hector’s Gobies are:
- Wide space between the eyes (67% to 90% of eye diameter),
- The back edge of the upper jaw lines up with the front edge of the eye,
- The first two dorsal-fin spines are elongated and thin,
- Scales on the body are small and ctenoid (tooth-like), but smooth in some areas,
- Predorsal scales don’t reach past the posterior edge of the eye,
- Cheek and opercle (gill cover) have no scales,
- The base of the caudal fin is covered in small, smooth scales,
- The base of the pectoral fin has about 4 to 9 vertical rows of fine cycloid scales, and
- The prepelvic area has cycloid scales, with 9 to 14 in the midventral row.
Other key characteristics that differentiate Hector’s Goby from other similar species are:
- Width at anal-fin origin: 9.9% to 10.7% of body length,
- Caudal peduncle depth: 75.4% to 88.9% of its length,
- Head depth: 47.3% to 54.4% of head length,
- Length of 11th-second dorsal-fin ray: 11.8% to 14.2% of SL, and
- Length of 8th anal-fin ray: 13.7% to 14.9% of SL.
