Common name: Broad-barred goby

General information

The Broad-barred Goby, Gobiodon histrio, is a small, brightly colored fish that is popular among reef aquarium enthusiasts. This species is known for its vibrant green coloration and the distinctive broad blue to black bars that run vertically across its body. They are relatively hardy and can be a good choice for both novice and experienced aquarists.

Care

Gobiodon histrio is a small fish that does not require a large aquarium, making it suitable for nano-reef setups. They thrive in well-established aquariums with plenty of live rock for hiding and foraging. Their diet should consist of a variety of meaty foods such as brine shrimp, mysis shrimp, and finely chopped seafood. It is important to feed them small amounts several times a day.

Reproduction

In the wild, Broad-barred Gobies are known to be monogamous and form pairs. They lay their eggs in small crevices or under overhangs in the coral. In the aquarium, breeding can occur if a compatible pair is established, and the environment is stable.

Symbiosis

One of the most interesting aspects of Gobiodon histrio is their symbiotic relationship with certain species of corals, particularly Acropora. They use the coral's branches for protection and spawning, and in return, they may help to keep the coral free from parasites and algae.

Habitat

The natural habitat of the Broad-barred Goby includes shallow coral reefs and lagoons in the Indo-Pacific region. They are often found in association with branching corals, which provide them with shelter and a place to spawn.
