Common name: roundfin goby

General information

The Bridled Goby, scientifically known as Bathygobius cyclopterus, is a small and fascinating fish species popular among marine aquarium enthusiasts. This species is known for its distinctive appearance, characterized by a mottled brown and white body with a series of dark, saddle-like markings across its back. The common name 'Cyclops Goby' is derived from the prominent dark spot, or 'eye spot', often present on the first dorsal fin, which can resemble the single eye of the mythical Cyclops.

Care

Bridled Gobies are relatively hardy and can adapt to life in captivity if provided with a well-structured environment that mimics their natural habitat. They thrive in tanks with plenty of live rock and sand substrates, which offer hiding places and surfaces for algae growth. These gobies are typically peaceful and can coexist with a variety of tank mates, but they may exhibit territorial behavior towards other bottom-dwelling fish. A varied diet of small invertebrates, such as copepods and amphipods, along with high-quality prepared foods, will help maintain their health and coloration.

Reproduction

In the wild, Bridled Gobies are known to exhibit a fascinating reproductive behavior where males prepare and guard nesting sites, often under shells or rocks, to attract females. After spawning, the male diligently guards the eggs until they hatch. In the aquarium, breeding these gobies can be challenging, but with careful attention to water quality and providing a stress-free environment, it is possible for hobbyists to witness their reproductive behaviors.

Habitat

Bathygobius cyclopterus is found in shallow, coastal waters, often in areas with rocky or rubble substrates. They are commonly associated with tide pools and mangrove swamps where they can dart among the roots and rocks. Their natural range extends across the Western Atlantic, from Florida and the Bahamas to Brazil, including the Gulf of Mexico and the Caribbean Sea.
