Common name: Cleaner goby

General information

The Yellowline Goby, Elacatinus genie, is a small, vibrant fish known for its striking yellow stripe that runs from the nose to the base of the caudal fin. This species is part of the Gobiidae family and is a popular choice for reef aquariums due to its peaceful nature and beneficial cleaning behavior.

Care

Yellowline Gobies are hardy and well-suited for captivity. They thrive in well-established aquariums with plenty of live rock for hiding and grazing. These gobies are known for their symbiotic relationship with larger fish, providing a cleaning service by removing parasites. They readily accept a variety of prepared foods, but should also be provided with live or frozen fare to mimic their natural diet.

Reproduction

In the aquarium, Yellowline Gobies may form monogamous pairs and spawn regularly. The male typically guards the eggs, which are laid in a sheltered location, until they hatch. Breeding these gobies in captivity can be a rewarding experience for advanced hobbyists.

Symbiosis

Elacatinus genie engages in a mutualistic relationship with larger fish species, offering a cleaning service by picking off parasites and dead skin. This behavior is not only fascinating to observe but also contributes to the overall health of the aquarium community.

Habitat

Native to the Western Atlantic, Yellowline Gobies are commonly found in shallow coral reefs, often in association with branching corals. They are adept at maneuvering through the complex structures of the reef, which provides them with protection and abundant food sources.
