Here are some shots I took a while ago. I was working on my lights, so my tank was in the dark for most of the day. When I turned the lights back on, there were a number of what I have called Spaghetti Worms (actually actually hair-worm, or cirratulid polychaete) on the front glass spawning. I wasn't able to get any pics of them spawning, but I did manage to get som nice shots of these worms.
