The Diamond Goby, Valenciennea puellaris, small brilliant orange diamond shapes across is pearl-descent white body. They are hardy and very peaceful and can be housed with other peaceful fish in a reef tank setting, but may become territorial towards other blennies, gobies or dartfish in smaller tanks.

Gobies tend to stay mainly towards the bottom of the tank, burrowing and sifting through the sand. However, this goby is also a known jumper, so a tightly fitting lid is suggested. Diet should include a variety of frozen or live mysis shrimp and vitamin enriched brine shrimp 1-2 times daily.

The Diamond Goby (Valencienna puellaris): A Jewel of Saltwater Aquariums

The Diamond Goby (Valencienna puellaris) is a remarkable species that adds beauty and functionality to saltwater aquariums. Known for its stunning appearance and beneficial behavior, this goby has become a sought-after choice among marine enthusiasts. Let's explore the Diamond Goby's habitat, reef-safe nature, size, lifespan, diet, aquaculture options, compatibility, suitable tank mates, tank requirements, other common names, and compatible tank mates.

Diamond Goby Habitat

The Diamond Goby is found in the tropical and subtropical waters of the Indo-Pacific region, including the Red Sea and the western Indian Ocean. In the wild, they inhabit sandy substrates and seagrass beds, where they spend their time burrowing and sifting through the sand for food.

Reef-Safe Nature of the Diamond Goby

The Diamond Goby is entirely reef-safe and poses no threat to corals or other invertebrates. They offer a valuable service to the aquarium by constantly sifting through the sand, helping to prevent detritus buildup and improve water quality.

Diamond Goby Size and Lifespan

Diamond Gobies can grow to be about 3 to 4 inches (7.5 to 10 cm) in length. With proper care, they can have a lifespan of up to five years in a well-maintained aquarium.

Diet and Feeding Habits of the Diamond Goby

Diamond Gobies are detritivores in their natural habitat, feeding on tiny organisms and particles found in the sand. In a home aquarium, they readily accept a diet of high-quality frozen or live foods like brine shrimp, mysis shrimp, and small pieces of fish or shrimp.

Aquaculture Options for the Diamond Goby

The Diamond Goby is available in the aquarium trade, and captive-bred specimens are slowly becoming available. Captive-bred gobies are more sustainable and help reduce the impact on wild populations.

Compatibility and Tank Mates of the Diamond Goby

Diamond Gobies are generally peaceful and can coexist with various tank mates. They are known to be docile and rarely exhibit aggression towards other fish.

Suitable Tank Mates for the Diamond Goby

  • Cardinalfish: Peaceful and colorful, cardinalfish make suitable tank mates for the Diamond Goby.
  • Firefish (Nemateleotris magnifica): These small and peaceful fish share a compatible tank environment with the goby.
  • Pseudochromis (e.g., dottybacks): Certain species of pseudochromis can coexist with the goby, adding color and personality to the tank.
  • Blennies: Some species of blennies are suitable tank mates that add character and charm to the aquarium.
  • Jawfish (Opistognathus spp.): Peaceful jawfish species can be compatible tank mates for the Diamond Goby.

Diamond Goby Tank Requirements

To provide a suitable environment for the Diamond Goby, the aquarium should have a soft sandy substrate that allows the goby to burrow and sift through the sand. Ample hiding spots and open areas for swimming are also appreciated.

Other Common Names for the Diamond Goby

Besides the name "Diamond Goby," this species is also known as the "Diamond Watchman Goby" or "Pretty Prawn Goby."

In conclusion, the Diamond Goby (Valencienna puellaris) is a jewel of saltwater aquariums. Its stunning appearance and beneficial behavior make it popular among marine enthusiasts. Aquarists can enjoy the beauty and functionality of these captivating gobies by providing them with a suitable environment, compatible tank mates, and proper care.

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

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.

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.

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.

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.

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.
