The Court Jester Goby, also known as Rainford's Goby or Old Glory, was initially identified in the Western Pacific in 1940 by Whitely. Its name stems from the vibrant colors that adorn its body. The Court Jester Goby boasts a striking combination of green and blue hues, accentuated by horizontal orange stripes that span the length of its body. This goby species is known for its timid and peaceful nature, making it an excellent choice for both reef and fish-only aquariums.

To provide a suitable habitat for the Court Jester Goby, it is recommended to house it in a well-established aquarium of at least 10 gallons or larger. The tank should be equipped with live rock and a sandy substrate, allowing the fish to graze. Ideally, it is advisable to keep only one individual of this species unless the aquarium is spacious enough to accommodate multiple individuals with ample hiding places. The Court Jester Goby rarely exhibits aggression towards other species.

In some cases, successful spawning of the Court Jester Goby can be achieved within an aquarium setting.

In terms of diet, the Court Jester Goby thrives on a combination of filamentous algae and small crustaceans. It is recommended to provide a varied diet that includes live and frozen brine shrimp, as well as mysis shrimp, to ensure their nutritional needs are met.
