Common name: Neon goby

General information

The Barber Goby, also known as the Yellowline Goby or Brazilian Cleaner Goby, is a small and colorful marine fish that is highly appreciated in the reefkeeping hobby for its cleaning behavior. Elacatinus figaro is part of the Gobiidae family and is endemic to the Atlantic Ocean, particularly along the Brazilian coast. This species is recognized for its striking yellow longitudinal stripe that runs from the eye to the base of the caudal fin, set against a contrasting dark body.

Care

Barber Gobies are small, reaching only about 5 cm (2 inches) in length, which makes them suitable for smaller aquariums. They are peaceful fish that can be kept with a variety of tank mates. However, they should not be housed with aggressive species that may harm them. These gobies prefer a well-established tank with plenty of live rock for hiding and foraging. They are carnivorous, feeding on small crustaceans and parasites on other fish, and in the aquarium, they will accept a variety of prepared foods.

Reproduction

In the wild, Barber Gobies form monogamous pairs during the breeding season. They lay their eggs in small crevices or under overhangs on the reef, where both parents guard the eggs until they hatch. In the aquarium, breeding these gobies can be a rewarding experience, although raising the larvae can be challenging due to their small size and specific dietary requirements.

Symbiosis

Elacatinus figaro is known for its symbiotic relationship with larger fish, offering a cleaning service by removing ectoparasites and dead skin. This mutualistic interaction not only benefits the 'client' fish by reducing their parasite load but also provides the Barber Goby with a source of food. In the aquarium, they may perform this cleaning behavior on tank mates, which is fascinating to observe.

Habitat

Barber Gobies are found in shallow reefs and rocky outcrops, typically at depths of up to 40 meters. They are often associated with coral and sponge growth, which provides them with shelter and foraging grounds. Their natural range is restricted to the Western Atlantic, from the state of Bahia to the south of Rio de Janeiro in Brazil.
