Algae Blenny, Salarias fasciatus

The Sailfin/Algae Blenny is notable for its unique looks and winning personality. With a mottled tan color, oversized eyes, and typical body shape of the Blenniidae family, Salarias fasciatus adds visual appeal to any marine aquarium. But despite its tendency to grow to an impressive 5" in size in the home aquarium, the Sailfin/Algae Blenny remains peaceful, active and, therefore, fun to observe.

Also referred to as the Jewelled Rockskipper, Lawnmower, or Rock Blenny, the Sailfin/Algae Blenny is native to the reefs across the Indo-Pacific. Like other Blennies, the Sailfin/Algae Blenny will perch on live rock, hide in caves, hop across the substrate, and graze on microalgae. Therefore, it requires a larger system with a variety of live rock and rockwork.

The Sailfin/Algae Blenny is peaceful towards other fish unless the tank mate is similar in shape or appearance to the blenny. It is best to house the Sailfin/Algae Blenny singly unless kept in a larger aquarium and the two are a mated pair. It is known to nip at small-polyped stony coral and clam mantles.

The Sailfin/Algae Blenny does best in well-established aquariums with large amounts of natural algae to feed on. The diet can be supplemented with vegetable matter, spirulina, and herbivore preparations.
