Common name: Rippled coral goby

General information

The Rusty Goby, also known as the Green Clown Goby or Rivulated Goby, is a small and colorful fish that is popular among reef aquarium enthusiasts. Gobiodon rivulatus is known for its vibrant green coloration and peaceful demeanor, making it a great addition to many saltwater aquariums. Despite its common name, the coloration of this species can range from green to rusty orange, depending on its mood and environment.

Care

Rusty Gobies are hardy and adaptable, but they do best in well-established aquariums with plenty of live rock for hiding and grazing. They are not aggressive and can be kept with a variety of other peaceful fish and invertebrates. These gobies are known to feed on small crustaceans and algae in the wild, so a varied diet including frozen and live foods, as well as algae-based foods, will keep them healthy in captivity.

Reproduction

In the aquarium, Rusty Gobies may spawn if they are kept in a pair or small group, and the tank conditions are to their liking. They lay their eggs in small crevices or on the ceiling of caves, where the male will guard and care for them until they hatch.

Symbiosis

While not as well-known for symbiotic relationships as clownfish, some Gobiodon species have been observed to associate with certain corals, potentially for protection and as a food source. However, the Rusty Goby does not have any specific symbiotic relationships that are significant in the aquarium trade.

Habitat

Gobiodon rivulatus is found in the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific. They typically inhabit shallow lagoons and coral reefs, often sheltering in branching corals like Acropora.
