This fish is a peaceful species that thrives in an environment similar to its natural habitat. It should be kept in a 10 gallon or larger aquarium that is well-established and has live rock and sand on which the fish can graze. It is best to keep only one of this species in an aquarium, as it is not known to be a social species and will likely exhibit territorial behavior. In a large tank with an abundance of hiding places, two or more of this species may be kept together. It is rarely aggressive towards other species, making it an ideal tank mate for a variety of fish.

The Court Jester Goby is an excellent choice for those looking to add a vibrant and lively fish to their aquarium. Not only are they beautiful to look at, but they are also known to be relatively hardy and easy to care for. It is possible for them to successfully spawn in an aquarium and they are considered a great choice for both novice and experienced aquarists. Additionally, they typically live in the wild for up to five years, making them an excellent choice for those looking to add a long-term resident to their setup. Furthermore, they are capable of coexisting peacefully with other tank mates and can be kept in groups with their own kind. All in all, Court Jester Goby is a great addition to any aquarium.

In order to achieve the best results, a diet rich in filamentous algae, small crustaceans, such as live and frozen brine shrimp, mysis shrimp, should be consumed.
