The Lawnmower Blenny is a useful algae eater with a quirky personality. Its mottled brown and green body provides excellent camouflage, paired with a sail-like dorsal fin and the ability to perch on rocks using pectoral fins. Native to the Indo-Pacific, from East Africa to Indonesia, they inhabit shallow reefs and lagoons with algae-covered rocks. Hardy once acclimated, they add entertaining behavior to the tank, often seen "mowing" surfaces clean.
