After stalking my vampire shrimp a bit I finally got a decent picture of him.
Some 4cm long (perhaps longer), still won't come out of his dad gum hole. Click the image for the full version - which is huge, but at least you see him in all his red-blue glory.

I just did a water change, wiped up that side of the tank and took two more pictures. Here's the better one, cropped:
