Common name: Doublebar goby

General information

The Two-banded Goby, Callogobius bifasciatus, is a small and attractive fish species that is well-suited for nano and smaller reef aquariums. Its distinctive feature is the two dark bands that run vertically across its body, which are complemented by a tan to yellowish base color. This species is not as common in the aquarium trade as some other gobies, but it can be a fascinating addition for those looking to diversify their tank inhabitants.

Care

Two-banded Gobies are relatively hardy and can adapt to life in captivity if provided with a well-established aquarium that mimics their natural environment. They prefer tanks with plenty of live rock and sand substrate, which offer hiding places and potential spots for burrowing. These gobies are peaceful and can be kept with other non-aggressive tank mates. They are carnivorous, feeding on small invertebrates and zooplankton in the wild, so a diet of meaty foods like brine shrimp, mysis shrimp, and finely chopped seafood is recommended.

Reproduction

In the wild, Callogobius bifasciatus is known to form monogamous pairs during the breeding season. They are burrow spawners, laying their eggs in burrows or crevices, which are then guarded by the male until they hatch. Reproduction in the home aquarium is not common, but stable environmental conditions and a well-structured habitat can encourage breeding behavior.

Habitat

The natural habitat of the Two-banded Goby includes shallow reefs and lagoons, often found in association with rubble and coral fragments. They are typically found at depths ranging from just below the surface to about 30 meters. Geographically, they are distributed across the Indo-Pacific region, from the Red Sea and East Africa to the central Pacific Ocean.
