Common name: Shortstripe goby

General information

The Sharknose Goby, Elacatinus chancei, is a small, vibrant fish that is a popular choice for reef aquariums due to its peaceful nature and cleaning behavior. It is characterized by its elongated body, bright yellow stripe running from the nose to the tail, and its propensity to perch on corals and rocks.

Native to the Western Atlantic, particularly the Caribbean Sea, this species is often found in shallow reefs and seagrass beds. It is known for forming symbiotic relationships with larger fish by setting up cleaning stations where it removes parasites and dead skin.

Care

Sharknose Gobies are hardy and well-suited for captivity. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. A varied diet of small meaty foods like brine shrimp, mysis shrimp, and quality marine flake or pellet food will help maintain their health and coloration.

Reproduction

In the wild, Sharknose Gobies are protogynous hermaphrodites, meaning they are born female and can change to male if necessary. They form monogamous pairs and lay eggs in small crevices. In the aquarium, breeding can occur if a stable pair is established, with the male guarding the eggs until they hatch.

Symbiosis

Sharknose Gobies are known for their mutualistic cleaning behavior, where they remove ectoparasites and dead tissue from other fish. This not only benefits their 'clients' but also provides the gobies with a source of food. They are often seen working on larger fish such as groupers and snappers.

Habitat

Elacatinus chancei is typically found in the coral reefs and seagrass beds of the Caribbean Sea. They prefer shallow waters where they can easily access both their food sources and the fish they clean.
