Out of Stock


The Diamond Goby (Valenciennea puellaris) is white with bright orange spots. It can be differentiated from the similar Orangespotted Shrimpgoby (Amblyeleotris guttata) by its white pectoral fins.

This fish is best known as part of the group of gobies known as sandsifter or sleeper gobies. They take mouthfuls of the substrate and sift it out through their gills, searching for food. This can help keep the substrate aerated, and may help prevent the build-up of organic debris that leads to high nitrate levels, algae, and cyanobacteria ("Red Slime Algae"). They should be kept in a tank with fine, soft substrate that will not damage their gills as they sift.

They will eat a variety of frozen foods and possibly flake and pellet. Gobies prefer a tank with plenty of rocky hiding places. They get along with most tankmates, but can be aggressive toward other gobies. When startled or threatened, they have been known to jump out of uncovered aquariums. Always keep the tank covered and provide plenty of hiding places for this fish to retreat to.

Good Sifter


Very aggressive toward other Sand sifitng Gobies and a few misc species, but does an amazing job at keeping the sand sifted. No more algae patches in the sand!



This is the best sand sifter ever! But it got eaten...(stupid brittle star!)

Hard to contain


Great fish to help keep the surface layer of substrate clean and loose, but it's a jumper. Although my aquarium is well-covered, this goby found his way out, and I didn't know it until he had become fish jerky. I suspect other specimens of this goby will have the same propensity. It's a great fish, if you can keep him inside your tank.
