Common name: Large sandgoby

General information

The Yellow Clown Goby, Fusigobius maximus, is a small, brightly colored fish that is popular among reef aquarium enthusiasts. Known for its vibrant yellow hue and peaceful demeanor, this goby is a great addition to many saltwater aquariums. It is a member of the Gobiidae family, which is known for its diverse and often brightly colored species.

Care

Yellow Clown Gobies are hardy and adaptable, making them suitable for both novice and experienced aquarists. They thrive in well-established aquariums with plenty of live rock for hiding and grazing on microalgae. These gobies are generally peaceful but may become territorial with others of their kind. A varied diet of small meaty foods and marine-based flake or pellet food will help maintain their color and health.

Reproduction

In the home aquarium, Yellow Clown Gobies may spawn if they are kept in a pair or small group, laying their eggs on the underside of coral branches or on the aquarium glass. The male typically guards the eggs until they hatch.

Symbiosis

While not involved in the classic anemone-fish symbiosis, Yellow Clown Gobies are often found perching on or near hard corals in the wild. They may form a mutualistic relationship with certain coral species, where the goby provides the coral with nutrients through its waste, while the coral offers shelter.

Habitat

Fusigobius maximus is found in the Western Pacific, from the Great Barrier Reef to the central Pacific islands. They inhabit coral-rich areas of lagoons and outer reefs, usually at depths of 1 to 30 meters.
