Lawnmower Blenny (Salarias fasciatus)

A workmanlike algae grazer that mows film and short hair algae off rock and glass all day long. Mottled brown camouflage with a comical perching posture, reaching about 5 inches. Reef safe. Needs an established tank of 30 gallons or more with algae to graze, supplemented with nori and spirulina once the rock is clean. Care level: easy.
