Yellowstripe Goby

Koumansetta hectori

The Yellowstripe Goby, known scientifically as Koumansetta hectori, inhabits the tropical waters of the Indo-West Pacific, ranging from the Seychelles to Fiji, and extending north to Japan and south to New Caledonia. This small reef fish is typically found in sheltered coral reefs at depths of 3 to 30 meters, though it is most commonly seen between 5 and 20 meters. The species is characterized by its elongated body and distinctive fin structure, with dorsal spines and soft rays that help divers identify it from similar species. In terms of diet, the Yellowstripe Goby feeds on a variety of small marine organisms. Its stomach contents often include filamentous algae, harpacticoid copepods, ostracods, amphipods, and nematodes. This goby tends to hover solitarily above sandy bottoms near reef bases, often in areas shaded by large corals. For divers encountering the Yellowstripe Goby, it presents a harmless and serene presence, often seen hovering a short distance above the substrate. Its conservation status is listed as Least Concern. The species is also part of the aquarium trade, valued for its unique appearance and peaceful nature.
