Bicolor Blenny
Ecsenius bicolor (Day, 1888)
A Bicolor Blenny at North Solitary Island, New South Wales.
The Bicolor Blenny lives in crevices on coral reefs.
Three colour forms are known. The fish in the image is the two-coloured form, which is bright orange posteriorly. The second form is dark brown all over, and the third form has a more complex pattern with a black and a white stripe along the body. All three forms have a curved pinkish marking behind the eye (difficult to see in the image).
The Bicolor Blenny is distributed from the central Indian Ocean to the western Pacific. In Australia it is recorded from the central Western Australian coast to northern New South Wales.
Including the elongated caudal fin, this species can grow to 11cm in length.
