H. lunulata (blue-ring) aggressive display

I can't remember if I've posted this before, but to bring a bit of holiday cheer, attached is a photo I took of a female Haplalochlaena lunulata threatening at another female that is behind her. The aggressive female is using what I've been calling the "umbrellla" display. You are looking at her ventral surface (mouth visible). This is not the surface that is displayed to the opponent. Still, the blue-rings showing through the web are interesting, so I thought I would share it.

No, but I have some the other way around. To date we just have digital video and that certainly wasn't taken in a photographic tank with clean water and good lighting. Every time that I've put them together, I was focused more on recording the behavior and not on documenting it photographically. If I can come up with a few blue-rings in the next couple of months, part of the plan is get some reasonable quality photographs.
