    Hi all

    This weekend when I woke up, my coco worm was missing from where it had been happily planted in the sand the past few months. After searching all over, we noticed part of it sticking out from under the long spine urchin. I tried picking the urchin up to get it out but to no avail, it just would not let go of the rock it was on. Eventually after irritating it a bit to get it to move did the tube fully come out.

    Sad to say, empty tube... no coco worm. Anyone come across this before? Urchins are great algea cleaners, never heard of them eating any of it's tankmates before?

    I would not throw the tube away...the coco worm might still be in there...they will pull inside (deep) to protect themselves and i dont think the urchin would have a shovel to dig the worm out.The tube worm might come back out after a couple of days even weeks.

    Thanks Zandy. The part that was under the urchin was broken open [split in half] so Im hoping that part of it and the worm stayed in the sand. None the less I left it in the tank just to be safe

    Urchins arent predators so wouldnt have eaten a coco worm.

    Yes, Urchin's are good for algae etc, but in my openion not really suited for Marine Tank's. Even tho they don't mean harm, they can easily move LR, go over coral,tube worms etc's...

    Your liverock should be scaped in such a way that an urchin does not unbalance it. Corals should also be fixed to liverock. Urchins are a good part of a cleanup crew in a reef tank. They remove corraline algae which to me is fantastic. In my tank I have three tuxedo urchins and two spiny urchins. Love them

    That's true I agree, If you planning on having urchin's in your tank it should be urchin proof, :thumbup:

    But I guess they just not for me then :p
