ID please (Nassarius snail tracks?)

[jgraz]

I have ssen a total of 3 of these pop up in the last couple of days. My nassarius snails left them behind. They come out of the sand and go up the tank walls and leave these behind. This is the only track that I can get a pic of, the other two are in bad spots for pics. Anyone have any clues?

Thanks in advance

Thanks, guess i'll leave them there. I guessing that most or all will get eaten by fish and hermits before making it
