Lethrinus Microdon - Small Tooth Emperor Fish; Is the subject of this shot, these fish are pretty tricky to get close as they are very fast and very skittish. I spotted this guy on a sand bar at between 12-13 meters at local dive-site, White Rock. As you can see in this shot these guys have an interesting camouflage, they have mottled and blotched markings in a shade of brown or a clean silver look as seen at the end of this shot. I have often observed these guys in small schools on the hunt, as they hunt they appear to flash their camouflage on and off as if they where communicating with each other.
The key to this shot is understanding the fishes behavior and controlling your approach, with the emperor respect his space and let him check you out, relaxing your breathing so that bubbles aren't scaring the subject and slowly approach to get closer.
