The Half-Barred Goby (Amblygobius semicinctus) is a beautiful goby found among the eastern Indian Ocean and western Pacific. They have a tan or white body with darker vertical stripes, a white underbelly and occasional blue markings. They can be found among lagoons or rocky quarries, where they hide among the sand/rock and search for small crustaceans in the substrate. In the home aquarium, they should be kept with a thick sand bed of at least 3 inches, so they can dig and search for food. They do best in established aquariums, as newer tanks may have little food/ nutrients in the sand. Their diet should consist of live copepods or cyclops, as well as frozen food, such as mysis or krill. They are peaceful and do well in reef aquariums. Reaching a maximum size of around 4-1/2 inches, they should be housed in an aquarium of at least 30 gallons. A lid is recommended, as they are capable of jumping.
