Sailfin or Lawnmower Blenny makes a great addition to the reef aquarium and is generally considered reef safe. They can grow up to 5 inches long and usually make great tank mates with other fish but may fight with other Blennys or fish with the same appearance. Blennys eat a mixed diet and are considered detritivores. Blennys will eat Nori, pellets and frozen meaty foods so be sure to keep them happy with a mixed diet. Lawnmower Blennys are usually olive to dark brown and change color to match their mood and surroundings. This unique looking fish makes a great addition to the reef aquarium.
