Was busy minding my own business, watching a small school of silver fish swim by when out of no where a Lizardfish grabs one of them and starts to try and swallow it whole. Great picture thought I as it settled on the bottom to enjoy its meal. I quietly approached lined up a great shot and squeezed the shutter, shutter lag kicks in, fish moves to new location just out of frame and picture taken of bare rock, bugger. This happened twice more before I finally get a fairly average shot and give up not wanting to harass too much. I backed off and watched, after a while it just spits it out and both swim off.

Later on I find another one just sitting in the coral, didn't mind me being there.

Was using a Nikon coolpix 5000 with a single Sea & Sea YS90DX
