Orange-Spotted Sandgoby

The Orange-Spotted Sandgoby, scientifically known as Fusigobius longispinus, is a small tropical marine fish commonly found in the Indo-West Pacific region, from the 🌊 Red Sea and East Africa to locations as far north as the Ryukyu Islands (🇯🇵 Japan) and as far south as the Great Barrier Reef. This species is typically associated with seaward coral reefs and prefers sandy bottom habitats within caves, dwelling at depths ranging from 9 to 25 meters (approximately 30 to 82 feet).

This fish is relatively small, reaching a maximum length of about 8 cm (roughly 3 inches). Its body is primarily whitish, adorned with evenly spaced, round orange spots. It features a triangular head with a short, pointed snout. Distinctive markings include around four patches on the sides of its body and a triangular patch at the base of its tail. All fins are primarily whitish, with orange spots prominently displayed on the dorsal and caudal fins.

The Orange-Spotted Sandgoby's dorsal fin is characterized by seven spines and nine soft rays, with its first spine notably elongated, particularly in mature males. The anal fin is supported by a single spine and has between seven to eight soft rays, sharing a similar shape to the second dorsal fin. The pectoral fins are quite large and extend beyond the origin of the anal fin, while the pelvic fins are cup-like and connected by a membrane.

This fish, with its spindle-like body shape, has no known significance to fisheries but is commercially sought after for aquariums due to its colorful appearance.
