Diamond Goby

The Diamond Goby is a marine fish known for its distinctive "sand-sifting" habit: it repeatedly takes mouthfuls of sand, filters out tiny organisms to eat, and spits the sand back out. This constant sifting helps keep the substrate clean and aerated, making it one of the hardest-working members of a reef tank's cleanup crew. Diamond Gobies are calm and peaceful, rarely troubling other fish, and settle in well whether kept singly or in small groups. Adults grow to about 10-15cm and typically live 3-5 years. Rated as beginner-friendly, this species suits first-time marine fishkeepers looking for an easygoing, low-drama addition to their aquarium.

About Diamond Goby

The Diamond Goby is a peaceful, beginner-friendly marine fish known for sifting sand to feed on microorganisms while keeping the substrate clean. Adults reach 10-15cm and live around 3-5 years.

7 things to know before welcoming a Diamond Goby

1Sand-Sifting Behavior
The Diamond Goby scoops mouthfuls of sand, filters out tiny organisms to eat, and expels the sand through its gills. This constant sifting keeps the substrate turned over and helps prevent waste buildup.
2Fine Sand Substrate Needed
Provide a bed of fine, powder-like sand so the goby can comfortably take it into its mouth and sift it. Coarse gravel makes this natural behavior difficult and can stress the fish.
3Peaceful Temperament
Diamond Gobies are calm and rarely aggressive toward other fish, making them suitable for community reef tanks. That said, they can be territorial toward their own kind or similarly shaped gobies.
4Watch for Jumping
Like many gobies, Diamond Gobies can startle and leap suddenly, especially when first introduced to a tank. Keep the aquarium covered or gaps sealed to prevent jumping accidents.
5Feed Frozen Foods Regularly
The microorganisms it sifts from the sand alone may not provide enough nutrition long-term, so regular feedings of frozen foods like brine shrimp help keep it in good condition.
6Needs Adequate Tank Space
Because it roams widely while sifting sand, the Diamond Goby settles in better in a tank with a reasonably large sand bed rather than a cramped space.
7Ease Into a New Environment
After being introduced to a new tank, it may hide and stay out of sight at first. Provide sheltered hiding spots and acclimate it gradually to avoid sudden changes in water quality or temperature.
