Hoese's Goby

Koumansetta hoesei

Hoese's Goby, a small reef-associated fish, is known for its distinctive coloration and pattern. It features longitudinal yellow stripes on the upper half of its elongated, compressed body. The head is brown on top and whitish underneath, with a yellowish white demarcation stripe extending from the jaw to the pectoral fin base. The first dorsal fin is marked by a dark red or red-brown ocellus with a black center. This goby inhabits tropical coral reefs in the Western Indian Ocean, specifically the Red Sea and the inner Gulf of Aden, at depths ranging from 3 to 26 meters. Typically found hovering just above the substrate in lagoons and seaward reefs, Hoese's Goby is usually solitary but can sometimes be seen in small groups. Its diet likely includes filamentous algae, copepods, amphipods, ostracods, and nematodes, similar to its close relative, Koumansetta hectori. The species is classified as Least Concern by the IUCN. Divers encountering Hoese's Goby may observe its solitary hovering behavior. Its distinctive coloration and patterns make it identifiable among other reef fish, though it tends to maintain a moderate distance from divers. Its small size, with males reaching up to 4.1 cm, adds to its subtle presence on the reef.
