Gobies are small scaleless fish in tropical oceans around the world. They are popular aquarium species, both for small tanks and for reef tanks. They are very easy to care for and eat a wide variety of aquarium foods.

Some of the gobies species cultured at ORA are known as cleaner gobies. They actively will pick parasites and other drebis from the body and gills of larger fish. Cleaner gobies will normally establish a cleaning station where other reef fish will gather to be cleaned. This characteristic carries over to aquarium life, and cleaner gobies can prove beneficial to their aquarium community.
