Bicolor Blenny

Bicolor Blenny

Ecsenius bicolor

The Bicolor Blenny lives up to its name with a sharply divided two-tone body — typically dark blue-grey in the front half and orange-yellow toward the tail. Growing to about 11 cm, it thrives in reef aquariums with plenty of crevices and caves, darting in and out with a curious, personable demeanor. May show aggression toward other blennies or similarly shaped fish.
