Bicolor Blenny (Ecsenius bicolor)

A blue grey front half fading into warm orange at the rear, with a curious face that perches on the rock and watches the room. Grazes film algae and reaches about 4 inches. Reef safe, though the occasional individual will nip at clam mantles or large polyps. Minimum tank 30 gallons. Diet: algae based foods plus mixed frozen. Care level: easy.
