Dorsal spines (total): 7; Dorsal soft rays (total): 15 - 17; Analspines: 1; Analsoft rays: 15 - 16

May feed on benthic organisms (Ref. 9360).

Inhabits sheltered bays and inner reefs on fine rubble shaded by large living corals (Ref. 48637). Occurs solitarily, hovering a short distance above sandy bottoms of reef bases. Stomach contents of one specimen comprise of filamentous algae, harpacticoid copepods, ostracods, amphipods, and nematodes (Ref. 9360).

Hector's goby (Koumansetta hector) is a species of goby native to the Indian Ocean (including the Red Sea) to the islands of Micronesia in the western Pacific Ocean. It can be found on sheltered coral reefs at depths of from 3 to 30 metres (9.8 to 98.4 ft) (though usually between 5 and 20 metres (16 and 66 ft)). This species reaches a length of 8.5 centimetres (3.3 in) SL. It can also be found in the aquarium trade. The specific name honours Gordon Hector (b. 1918) who was Chief Secretary to the Government of the Seychelles, in gratitude for his help to Smith's work in the Seychelles.
