Diamond Goby Fish

Approx. Size: 2" to 4" The Diamond Goby (Valenciennea puellaris) is a hardy and beneficial saltwater fish known for its sand-sifting behavior and striking appearance. With its elongated body, shimmering silver-white coloration, and orange diamond-shaped markings, this goby adds both beauty and functionality to a marine aquarium. Tank Requirements Diamond Gobies require a tank of at least 30 gallons, though larger tanks with a deep sandy substrate are preferred to support their natural burrowing and sifting behaviors. They thrive in well-established aquariums with plenty of hiding spots, such as rock caves and ledges, to help them feel secure. Sand-Sifting Behavior One of the biggest benefits of keeping a Diamond Goby is its ability to aerate and clean the sand bed. It constantly sifts through the substrate in search of food, preventing detritus buildup and helping to maintain a healthy aquarium environment. A fine to medium-grade sand bed at least 2-3 inches deep is ideal. Sensitiv
