Sipunculids- aka Peanut Worm

The Sipunculids- aka Peanut Worm feed on detritus, microscopic organisms and organics they extract from the sand. The peanut worm burrows into soft rocks and crevices often hiding during the day and coming out at night to feed. They reproduce sexually and given the right conditions can become quite abundant. I have recently discovered many in my tank and had a rare opportunity to photo one as it looked for food.

If anyone has any pictures or additional information they would like to share on the Peanut Worm, please feel free to post it here.

can you repost the pics?

yes, please do repost them. I think that is what I have in my sand. It is attached to the glass under the sand. I pulled one out of the sand and it has a soft white outter shell and rolled up kind of like a rolly polly but not all the way closed. When I dropped it back in the water it moved under the sand again and attached to the glass.
