The Knight Goby, scientifically known as Stigmatogobius sadanundio, is a unique and interesting species of freshwater goby. It is native freshwater habitats in South and Southeast Asia, including countries like India, Bangladesh, Myanmar, Thailand, and Indonesia.

The Knight Goby has an elongated body with a slightly compressed shape. It typically reaches a maximum size of around 4-5 inches (10-12 cm) in length. The coloration of this goby can vary, but it generally has a silver or grayish body with a series of dark vertical bars or stripes running along its sides. The fins may have some reddish or orange accents.

One distinctive feature of the Knight Goby is its ability to change colors based on its mood or environment. It can darken or lighten its body coloration, which adds to its overall charm and adaptability. This goby has large eyes and a downturned mouth, giving it a unique facial appearance.

In terms of care, the Knight Goby is relatively hardy and can adapt to a range of water conditions. It is adaptable to both freshwater and slightly brackish water, although it tends to prefer brackish conditions. It requires a well-maintained aquarium with good filtration and regular water changes.

Water parameters for the Knight Goby should be maintained within certain ranges. It prefers a pH between 7.0 and 8.0 and a temperature range of 72-82°F (22-28°C). If kept in brackish water, a specific gravity of around 1.005 to 1.010 is suitable. It's important to research and replicate the specific water conditions of their natural habitat to ensure their well-being.

As for tank setup, the Knight Goby appreciates a tank with plenty of hiding places and caves. Providing rocks, driftwood, or PVC pipes can create suitable hiding spots for them. They are not known for being aggressive, but providing hiding places helps them feel secure. Adding some smooth substrate, such as sand or fine gravel, is also beneficial.

In terms of diet, the Knight Goby is primarily a carnivorous species. It will eagerly consume live or frozen foods like bloodworms, brine shrimp, and small crustaceans. It may also accept high-quality pellets or flakes, but it's important to offer a varied diet to ensure their nutritional needs are met.

When it comes to tankmates, the Knight Goby is generally peaceful and can be kept with other non-aggressive fish that are not small enough to be considered prey. However, it's always important to observe their interactions and make sure tankmates are compatible.


To maintain the highest quality, all fish undergo a one-week quarantine upon arriving at our warehouse before being made available for sale. This practice helps ensure the health and well-being of the fish we offer to our customers.

Live aquatic life is exclusively shipped on Mondays, Tuesdays, or Wednesdays. If an order is placed between Wednesday and Sunday, it will be held until the following Monday, unless overnight shipping is selected. This schedule might change due to holidays or other unforeseen circumstances 

As with all live animal sales, there is a risk that they may arrive dead (DOA). If this is the case then a picture of the dead fish WITHIN THEIR ORIGINAL UN-OPEN BAG must sent to us. (

If the fish die anytime after they are released into their tank, that responsibility falls on the owner and no refund can be provided. 

Furthermore, to qualify for the Live Arrival Guarantee, you must be present to receive the fish during the first delivery attempt. If you will not be home for delivery we suggest you arrange for the delivery service to hold your package at their facility for pickup, allowing the package to sit on your porch in extreme hot or cold weather is obviously not the best option for your new aquatic life.
