About This Species
The Bicolor Blenny is a popular and entertaining fish with a distinct two-toned body: a dark, purplish-blue front half and a bright orange-yellow back half. They are full of personality, spending their time perching on rocks, peeking out of holes, and grazing on algae. They require a tank with mature live rock to provide both food and shelter. While peaceful towards most fish, they can be highly territorial and aggressive towards other blennies or fish with a similar body shape. A fascinating behavior is their 'perching,' where they use their modified pelvic fins to sit upright on surfaces, much like a person sitting on a stool.
