It requires a 10 gallon or larger aquarium preferably with branching coral. It will rarely become aggressive towards other fish, but will fight with its own kind in smaller tanks. Therefore, it is best if it is kept with other docile species.
It is common for clown gobies to spawn in an aquarium. Caution should be exercised if the aquarium contains Acropora sp. or similar SPS corals. They will lay their eggs on the underside of the coral's branch, which will cause tissue recession in that area of the coral. However, under good conditions, the coral will regenerate the lost tissue.
The Green Clown Goby's diet should consist of a variety of brine shrimp, frozen mysis shrimp, table shrimp, and frozen food preparations for carnivores.
