Thanks all.
It is cropped but only very slightly to balance the image better, as it was really a grab shot as it came in to see the reflection in the port glass. I have a closer shot, but blurry as it came well inside the minimum focal distance

I had no clue to the fury mouth until I found this one clearing out its mating patch on a little shelf on a wall dive around Halmahera Island Indonesia. Knowing they are not as aggressive as their bigger cousins I spent a while with it, watching it go about the business of preparation.
I think Chiang was on this dive with me too.
