The Flametail Blenny, Enchelyurus flavipes, features a characteristic yellow dorsal fin coupled with jet black body. 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.
This blenny is known as a rock skipper and has incredible jumping abilities, so having a tightly secured lid is suggested. Diet should include a variety of mysis shrimp and vitamin enriched brine shrimp as well as spirulina, marine algae, seaweed and algae based foods 2-3 times daily.
