The Golden Sailfin Blenny, Atrosalarias fuscus, has solid yellow or gold coloration, along with a noticeably long dorsal fin. They are hardy and can be housed with other peaceful fish in a reef tank setting, but may become territorial towards other blennies, gobies or dartfish in smaller tanks.

Blennnies are known for their incredible jumping abilities, so having a tightly secured lid is suggested. Diet should include a variety of spirulina, marine algae, seaweed and algae based foods 2-3 times daily.
