The Diamond Watchman Goby, also known as the Diamond Goby or the Orange Spotted Goby, is a small and colorful fish that is popular in the saltwater aquarium hobby. Its scientific name is Valenciennea puellaris. Here are some key characteristics and information about the Diamond Watchman Goby:

Appearance: The Diamond Watchman Goby has a slender body with a vibrant orange coloration. It has a white or light blue diamond pattern on its body, which gives it its common name. The fins of the goby are generally transparent.

Size: These gobies typically grow to around 3 to 4 inches (7.6 to 10 cm) in length, although some individuals can reach slightly larger sizes.

Behavior: Diamond Watchman Gobies are known for their interesting burrowing behavior. They are excellent sand sifters and spend much of their time sifting through the substrate in search of food. They help to aerate the sand bed and consume small invertebrates and organic debris.

Compatibility: They are generally peaceful and can be kept in a reef or community aquarium with other peaceful fish. However, they may show territorial behavior towards other goby species or similar-shaped fish. It is recommended to provide plenty of hiding spots in the aquarium, such as rock caves or coral branches.

Aquarium Requirements: A suitable aquarium for the Diamond Watchman Goby should have a sandy substrate of at least 2 to 3 inches (5 to 7.6 cm) in depth, as they like to dig and burrow. The tank should also have plenty of live rock or other structures that provide hiding places. They prefer a well-established aquarium with stable water conditions.

Feeding: These gobies are carnivorous and feed primarily on small invertebrates, such as worms, small crustaceans, and other tiny organisms found in the sand bed. In a home aquarium, they can be fed a varied diet consisting of high-quality frozen or live foods, including brine shrimp, mysis shrimp, and finely chopped seafood.

Care Level: The Diamond Watchman Goby is considered to have a moderate care level. While they are not overly difficult to care for, they do have specific requirements, such as a sandy substrate and a suitable diet.

Overall, the Diamond Watchman Goby is a beautiful and fascinating fish that can make a great addition to a saltwater aquarium, especially for those interested in observing its unique burrowing behavior.
