The Diamond Goby, Valenciennea puellaris, also known as the Pretty Prawn, Orange-Spotted Diamond Goby or the Orange-Spotted Sleeper Goby, features small brilliant orange diamond shapes across is fluorescent white body. They are one of the most beautiful species of goby for the home aquarium. Reaching a max size of 6", one should be kept in a tank no smaller than 30 gallons. A larger tank is needed if keeping a mated pair.
The Diamond Goby is constantly sifting through the sand to help keep it aerated, therefore a tank with a deep sandy substrate is recommended. They are also known for jumping, so a tightly fitting lid is necessary for the tank these gobies are kept in. They are peaceful and can be kept with other peaceful and reef safe fish. Though they can be territorial with other burrowing gobies, so they are best kept individually, or as a mated pair.
The Diamond Goby is hardy, easy to care for, and disease resistant. They will eat a carnivorous diet including both mysis and brine shrimp, as well as sift through the sand and scavenge. They will thrive in a temperature range of 72-78°F and a pH of 8.1-8.4.
A well oiled beautiful little machine. He hid about a day after acclimation but after he dug a little burrow he came out one morning and cleaned 90% of the sand, spotless. The 10% he didn't clean is next to the long tentacle anemone, can you blame him? Awesome sand sifter and does not create sand tornado's. Great personality.
The Diamond Goby is one of the best additions to my 30 gallon reef tank.
He sifts the sand, filters out the food on the bottom and generally keeps the tank clean. He will move the sand from under the live rock so it's best to keep the base rock close to the glass bottom so he cannot get under it to much.
When I added him to the tank he was initially shy, now he goes for food, burrows, and stares at you.
Diamond Gobies are my favorite addition to any tank. They are loaded with personality, and once they get comfortable, they will come out at all times of the day. Not only are they beautiful, they do a great job of keeping you sand clean, and it is fun to watch them filter the substrate out of the sand through their mouths/gills.

Really hardy, very busy fish, this one has done a great job at cleaning up my sand bed and he is a blast to watch. He likes to pick up the small snails and crabs and put them in a pile! Appears very healthy and doesn't fight with other fish.
I was surprised that in the description nothing was mentioned about the goby's penchant for sand sifting. Simply love this about this goby. Understatement about this goby having lots of personality. He came out of the burrow within an hour of being introduced to the his new home. Simply love this new addition to my tank. May get more.
When my wife and I was at a fish store I was looking at the different kinds of fish for the aquarium and my wife and called me over to look at my diamond gobi who was at the time beating up the one that was in the same tank
He beat the other one up until it jumped out of his tank to the next one and that was when I told the lady who was helping us with our purchase that I will most definitely buy him and I have never seen happier
He is really amazing and very enjoyable to watch as he does his land scrapping around the tank
I can watch him for hours and I think he try’s to mooch some more brine shrimp off me
