Clown Goby

Microgobius gulosus

The Clown Goby, known scientifically as Microgobius gulosus, is a small reef fish belonging to the goby family. This species is easily recognized by its light grey-brown body, which often features bright iridescent blue and yellow markings. It has a unique body structure with a laterally compressed shape, a large, nearly vertical mouth, and a completely scaled body. The first dorsal fin is characterized by seven spines, and its ventral fins are united, giving it a distinctive appearance among gobies. Clown Gobies are found in the western Atlantic, ranging from Maryland to southern Florida and Texas in the USA. They inhabit mangrove streams with fine silt-mud substrates, where salinity can vary widely from 0.0 to 36.6 ppt. These fish are typically found at depths of up to 75 meters, although most records indicate they are usually seen at shallower depths, often less than 10 meters. As benthic spawners, Clown Gobies lay their eggs on the substrate, where they develop. Divers encountering this species may find them in mangrove environments, where they are harmless and pose no threat to humans. According to the IUCN Red List, the Clown Goby is categorized as Least Concern.
