Concerning your comment about the commensal shrimp [#15824], here's an old photo with a single shrimp. I have another with a second shrimp but there's a ton of backscatter in it!

Yes this is almost certainly Periclimenes imperator. It is darker red and the white patches are reduced to small streaks in your animal, but otherwise the colour pattern is identical [see message #14726].
