For several months, I have had an unidentified invert in my 30g reef. It moves fast, so I have thus far been unable to get a picture of it. I only see it occasionally, and by the time I am aware of it, it burries itself in the sand. I was flipping through a biology textbook this evening, and when I saw a photo of a lancelet, my unidentified invert immediately came to mind. It looks exactly like a lancelet, but I have never heard of anyone having a lancelet in their tank. Anybody think it's possible?
