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.
