Jewelled Blenny, Salarias fasciatus

The Jewelled Blenny (Salarias fasciatus) is a well-known marine aquarium fish species in Australasia. In spite of being also known as the lawnmower blenny because of its propensity to consume algae growth from glass and rocks, it is mostly a detritivore, with plant material forming only 15 percent of its diet. This species reaches a length of 5.5 inches total length. The lawnmower blenny is usually regarded as compatible with the majority of other marine fish species and as a group with other lawnmower blennies.

The fish has a number of pale spots with dark streaks on the anterior portion and several dusky colored bands.

Its distribution is mainly in the Indo-Pacific range in areas including the Red Sea and East Africa to Samoa, north to the Ryukyu Islands, south to the Great Barrier Reef and New Caledonia.

They inhabit reef flats as well as shallow lagoon and seaward reefs. It can also be found in estuarine areas that have patches of rubble that are rich with algae on reef flats and slopes. They can normally be found in areas of mixed coral, sand, and rubble. They are found solitary in weedy areas on rocks and coral outcrops.

This fish is capable of blending in with is surroundings to hide itself from predators. It remains mostly on the ocean or aquarium floor or on any rocks or corals.
