The Lawnmower Blenny, or Algae Blenny, is an active saltwater fish from Fiji and Indonesia. They are VERY fun to watch and get their name “lawnmower” because they are also scavengers and will eat algae. Lawnmower Blennies are very cool looking as well, with a tan color, big eyes, and rounded body. They are peaceful fish and will not bother other tank mates. It is best to house them as singles unless you have a large aquarium and the two are a mated pair.
When setting up an aquarium for the Lawnmower Blenny you will need to keep a few things in mind. First, make sure your aquarium is established and has some natural algae because they will feed off of this. Also, make sure to have live rocks and caves that they can hide in and graze on the microalgae. Have fun with these cool little guys, they are so fun to watch!
