When I got home from work tonight, I noticed a very small (1cm max) thing darting around my aquarium. I couldn't really get a good look at it, but I would say it looked "wormish" if I had to. It was extremely fast and kept trying to burrow into the live rock.
Any ideas? I'm new-ish to saltwater aquariums, so this might be obvious and I just don't know! Thanks in advance.
**Edit: I captured the little bugger on film. It burrowed into a little hole and I got the tail end of it sticking out.**
