Behavior: The Orange Spot Diamond Goby is a hard worker and will keep the sand well sifted and clean. It takes large mouthfuls of sand and sifts through it eating small invertebrates and expelling the sand out of its gills. The Orange Spot Diamond Goby is best kept singly or in pairs unless added to a large reef aquarium of 200 gallons or more. They are rarely aggressive towards other fish and will do best in a reef aquarium with other peaceful fish. Make sure to provide substrate of fine consistency that they can sift through. A refugium will provide an added source of copepods and amphipods to supplement its diet.
Keep a lid on your aquarium because the Orange Spot Diamond Goby is very likely to try to jump out.
Feeding: Offer the Orange Spot Diamond Goby a mixed diet of mysis shrimp and herbivore preparations 4-6 times per week. Soaking all fish food with vitamins will help keep your fish healthier and make them less susceptible to disease. We recommend soaking food in garlic as well when adding new fish and whenever your notice ich or other disease in the aquarium. Garlic will help repel external parasites and will boost the fishes immunity.
Feeding Tips: Remember to feed slowly. Leftover food will cause nitrates and phosphates to rise. If you see food falling to the sand bed and into the rocks you should feed slower and give the fish a chance to eat before adding a little more. Using a turkey baster allows you to target food to different fish. For example you can feed the aggressive fish on one side of the tank and then squirt a little bit on the other side for the less aggressive fish. This way all the fish get a chance to eat enough.
Maximum Length: 6"
Care Level: Easy
Reef Compatibility: Excellent
Minimum Aquarium Size: 30 gal.
Range: Fiji, Indo Pacific, Indian Ocean
Water Conditions: 75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates, < .10ppm
Water Chemistry: Maintaining Ammonia at 0 ppm, Nitrites at 0 ppm, and Nitrates below 10ppm will help to keep your Orange Spot Diamond Goby happy and healthy. We recommend doing a water change soon after Nitrates rise above 10 ppm. Maintaining proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing), and magnesium levels (1260-1350 ppm) will help to keep pH stable in the 8.1-8.4 range. We recommend a specific gravity of 1.024-1.026 with 1.025 being ideal for fish. Temperature should remain stable as well and should stay within a 2 degree range.
