A two-eyed blenny peeping out of an ascidian at Batsata Maze.
These elusive fish like to hide out in holes and crevices, and often dart deep inside when startled by things like curious underwater photographers.
This was the case when I approached this particular blenny, so I quickly changed my focus light to the red setting and waited patiently until I saw the fish wearily making its way out to investigate its surroundings.
