About this species
Salarias fasciatus, commonly known as the jewelled blenny or lawnmower blenny is a benthic, neritic, marine fish species endemic to Australasia. Despite being known as the lawnmower blenny, due to its propensity to consume algae growth in aquaria, it is principally a detritivore, with plant material making up only about 15% of its diet. The lawnmower blenny camoflauges itself with its surroundings, even changing color to hide from predators.
