General DescriptionThe Orange-spotted sand-goby, also known as the White-flag sand-goby or Longspine goby, belongs to the Gobiidae family Fusigobius. This species is native to the Indo-West Pacific region, ranging from the Red Sea and East Africa to the Marshall Islands, north to the Ryukyu Islands, and south to the Great Barrier Reef. With a maximum size of 8.0cm, these gobies are generally small fish that inhabit the bottom areas of the ocean.
Aquarium SuitabilityConsidered suitable for aquariums, Orange-spotted sand-gobies are described as docile but may exhibit aggression towards similar species. They do best without other members of their species in the tank and thrive in environments with good hiding spots, such as between live rocks. Additionally, these fish filter sand to forage for food, aiding in keeping the sandy substrate clean, though not as efficiently as other sand-dwelling gobies.
Care and HardinessCategorized as having average hardiness, this species requires frequent feeding several times a day, especially when newly introduced to the tank. When natural food sources are available in the aquarium, they may need feeding less often. Orange-spotted sand-gobies' shy and docile nature necessitates caution when housed with more aggressive tank mates.
Reef SuitabilityOrange-spotted sand-gobies are deemed reef safe, making them suitable additions to reef aquariums without posing a threat to coral or other invertebrates.
Aquarium SetupWhen setting up an aquarium for Orange-spotted sand-gobies, it is essential to provide hiding places like live rocks, ensuring the fish feel secure in their environment. Maintaining water conditions within the parameters of a pH range of 8.1-8.4, a specific gravity of 1.020-1.025, a temperature range of 22.2-25.6°C, and a KH of 8-12 is crucial for their well-being. A minimum tank size of 100 liters is recommended for accommodating their needs adequately.
BehaviourOrange-spotted sand-gobies are generally shy and docile fish that may display aggressiveness towards members of their species. Providing ample hiding spots will help them feel more comfortable in the aquarium environment.
Feeding and DietThese gobies have a recommended diet that includes small crustaceans like krill, mysis, and artemia, as well as zooplankton such as Cyclops and pods. Their feeding routine should consist of multiple small meals throughout the day, especially during the initial acclimation period.
DimorphismNo information provided concerning dimorphism or captive reproduction of the Orange-spotted sand-goby.
Habitat and DistributionFound in the West Indian Ocean, Australia, Japan, the Red Sea, Indonesia, and various parts of the Pacific, the Orange-spotted sand-goby inhabits sandy substrates in tropical marine environments. Its range extends from East Africa to the Marshall Islands, encompassing diverse habitats within the Indo-West Pacific region.
