The Lawnmower Blenny, Salarias fasciatus, also known as the Algae Blenny, Sailfin Blenny, Jeweled Blenny, Jeweled Rockskipper. These Blennies are a beneficial and active member in any aquarium. They are a brownish color with various spots making them excellent at camouflage. The Lawnmower Blenny is long and slender with one dorsal fin extending the length of the body. It exhibits a blunt head with eyes perched at the top with scattered blue dots speckling the face. What makes the Lawnmower an excellent fish for any tank is its beneficial habit of eating away unwanted algae. They require little care and little direct feeding as they can often survive on what is found naturally in the tank. The Lawnmower Blenny can reach a size of 5.5 inches, and should be kept in a tank no less than 30 gallons. They should be housed in a tank with plenty of live rock, and an abundance of algae growth. Often, the Lawnmower Blenny will sit at the bottom of the tank scraping rocks and the walls of the tank with its specialized teeth searching for algal deposits. And they should be fed a herbivore diet.It is recommended to regularly feed Nori as a marine algae supplement. If underfed it may pick at small Polyp stony corals. So this should be monitored. Because the the Lawnmower Blenny is a prolific jumper, it is highly advised to have a tightly sealed lid on your tank to prevent escape. Overall, there is a reason that the Lawnmower Blenny is one of our best sellers and one of the most abundant species in the aquarium trade. They are funny, hardy, incredibly easy to keep, active, and beneficial. They are also extremely peaceful, and should be housed with other peaceful tank mates. But not recommended to be housed with very sensitive species, like Pipefish or Seahorses. We highly recommend this fish for anyone looking for an easy to keep fish for a beginner tank. They will thrive in a temperature range of 72-78°F and a pH of 8.1-8.4.
Acclimated well and is busy picking at the glass and live rock. Gets along fine with the other fish and corals.
