Care
Citrinus Clown Gobies are hardy and can adapt to a variety of tank conditions, but they thrive best in well-established aquariums with plenty of live rock for hiding and grazing. They are small, reaching only about 3 inches in length, so they don't require a large tank. However, they do appreciate a mature tank with stable water parameters. These gobies are not picky eaters and will accept a variety of foods including frozen and dried preparations.
Reproduction
In the aquarium, Citrinus Clown Gobies may spawn if they are kept in a pair or small group. They lay their eggs in crevices or on the underside of coral branches, where the male will guard them until they hatch. The larvae are planktonic and can be challenging to raise due to their small size and specific feeding requirements.
Symbiosis
While not involved in a symbiotic relationship as intimate as clownfish and anemones, Citrinus Clown Gobies are often found living among the branches of stony corals in the wild. They may help control pests like Acropora-eating flatworms, which can benefit the health of the coral.
Habitat
Citrinus Clown Gobies are native to the Indo-Pacific region, where they inhabit coral-rich areas of lagoons and outer reefs. They are typically found at depths ranging from 1 to 15 meters, often associated with branching corals like Acropora.
