I recently changed from rocks to sand since they like to dig. I used some construction grade sand that I sifted and cleaned before using. Seems to be fine and the triops like it. Anyway, this morning I was looking in the tank and saw a little red worm come about half way out of the sand and snag something (food?), then it went back into the sand. I stirred the sand up where I saw it to see if I could see it again, but no luck. Anyone know what it is?</blockquote>
