Known also as a Rock Blenny, a Jeweled Rockskipper and a Sailfin Blenny, this fish is found in the Indian Ocean and the Red Sea. It has a slender, elongated, green with cream mottling, body and a dorsal fin that covers the entire length of its body. This fish is named "lawnmower" because of its ability to "mow" hair algae. It also eats film and filamentous algae in a reef aquarium. This bottom swimmer is easy to find and very popular with reef aquarists.
Size: 2" to 3"; can get up to 5"
No in Tank: ONE! With a large tank, a mated pair can be kept.
Tank: min. 30 gallon
Temperament: Peaceful, except to blennies with a similar body shape. Can get aggressively territorial and, as an adult, it may become quarrelsome and attack tangs, angels and other large fish.
Food: (Herbivore) Primarily eats algae, yet a varied diet including a frozen herbivore preparation, vegetable matter and Spirulina,should be offered. If the aquarium is not supplying enough natural algae, this fish should also be offered algae sheets. When there is not enough algae or a well-established reef system, it will die of starvation.
Adaptation: Needs three or more hours to acclimate. Must have a well-established reef system with a large amount of natural algae, else this fish may not survive. It also needs plenty of hiding places and room to swim on multiple layers in the tank.
Compatibility: Ideal for reed systems. Will nip at small polyped stony coral and clam mantles as adults. This fish does not get along with blennies that have the same or similar body type: slender and elongated.
