Court Jester Goby

The Court Jester Goby, *Koumansetta hectori*, is a vibrant and engaging addition to any beginner marine aquarium. Reaching a maximum size of approximately 4 inches, this small but charismatic fish is native to the Indo-Pacific region. Its striking coloration, featuring alternating bands of bright yellow and deep blue or black, earns it its common name.

A minimum tank size of 10 gallons is suitable for a single Court Jester Goby, with larger tanks recommended for keeping multiple individuals or with other tank mates. They are generally peaceful and can be housed with a variety of non-aggressive marine fish and invertebrates. Providing ample live rock with crevices and hiding places is essential for their well-being, as they are known to be shy and appreciate having safe retreats.

In the aquarium, the Court Jester Goby will readily accept a varied diet of small, meaty foods such as enriched brine shrimp, mysis shrimp, and finely chopped seafood. Offering a diverse diet will help maintain their vibrant colors and overall health. They are often seen sifting through the sand or substrate in search of small invertebrates. While they are not known to host anemones, they may form a symbiotic relationship with certain types of shrimp.
