The Algae or Lawnmower 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 Algae Blenny remains peaceful, active and, therefore, fun to observe.
Like other Blennies, the Lawnmower Blenny will perch on live rock, hide in caves, hop across the substrate, and graze on microalgae. Therefore, it requires a system with a variety of live rock and rockwork.
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.
