Difficulty

Easy

Temperament

Semi-Aggressive

Description

A small combtooth blenny with a striking two-tone body, the front half dark blue to brown, the rear half bright orange-yellow, and large expressive eyes set on a blunt head. It perches on rock and hops from ledge to ledge, grazing film and filamentous algae, and is generally peaceful but territorial toward other blennies, gobies and dartfish in small tanks. Provide at least 30 gallons with abundant live rock, crevices and holes for hiding, feed algae-based foods regularly, and use a tight-fitting lid since it will jump.

Reef Safe

With caution

Environment

This species prefers a well-established tank with plenty of live rock for hiding and grazing. They thrive in tanks with a moderate to high lighting level and a gentle to moderate water flow.

Behavior

Bicolor Blennies are peaceful fish that love to perch on rocks and coral. They are known for their playful and curious nature, often seen swimming in and out of rock crevices and holes.
