Not where I expected it, a tiny cavity in an otherwise sheer rock wall covered with sponge. It was red… A flash bright red in the dive light had my attention quickly. I could not see the fish well enough to ID it, red is uncommon enough that I set up and fired anyway, just taking a photo was hard enough in the surge.

Only after downloading the photo I realized it was a scarface blennie…
