The Citron Goby, also sometimes referred to as the Citrin or Clown Goby, is a small yellow fish with blue vertical lines around the eyes and gills, and a blue horizontal line along the dorsal fin.

It requires a 30 gallon or larger aquarium and prefers branched corals, often resting on them for hours at a time. It will rarely become aggressive towards other fish, but will fight with its own kind in smaller tanks. It is best if it is kept with other docile species.

It will spawn while in the aquarium, laying eggs that sink into the coral branches where they are protected, however, the young have rarely been reared successfully.

The diet of the Citron Goby should consist of a variety of brine shrimp, frozen mysid shrimp, and table shrimp. Once acclimated, some will accept frozen food preparations for carnivores. If housed in a reef tank, it needs to be fed once a day. If housed in a tank without substrate, it will require several feedings per day.
