Salarias fasciatus (jewelled blenny) is a popular marine aquarium fish species in Australasia. Despite being also known as the lawnmower blenny due to its propensity to consume algae growth from rocks and glass, it is principally a detritivore, with plant material making up only 15% of its diet. This species reaches a length of 14 centimetres (5.5 in) TL. The lawnmower blenny is generally regarded as compatible with most other marine fish species and as a group with other lawnmower blennies.
The lawnmower blenny blends in with its surroundings, changing color to hide itself from predators. It stays mostly on the ocean or aquarium floor or on any rock or corals.
