    I got 4 of these. Normally they sit with just the head exposed like the one front right. But for some reason last night they were extended a lot more.

    They live in my DSB, so sorry for the dirty glass. Head is about R1 coin size. Their bodies is rather long, and reach very far into the sand. I do feed them once a week while feeding the bubble tip anemones in my display, a very small piece of hake or whatever the anemones are getting. They normally grabs it and pulls back into the substrate.

    Any idea as to whats their real name?

    nope, never.
    a lot smaller.
    No mucous membrane
    Only one set of tentacles at the oral disk rim.

    Not Isaurus zoanthids? Hard to make out with the pic. They do open up at night or sometimes when there is food in the water.

    nope, they are individuals. Each one on its own. When dug out, they look like a think worm. Pulled back together and white.

    They are a bit light shy when light is switched on. And can pull back into the sand when disturbed. But otherwise they are out extended.

    I cleaned the glass and the front ones pulled back in, will take another picture when out later

    @Lord_Blackadder
    2 of them are still in hiding an hour later after cleaning the glass a bit.

    The one in front out of focus just barely have its disk sticking out of the sand. The one at the back can see its tentacles better. Slight red tint. This is how they are normally, not sticking out of the sand.

    I would also like to know. I have two in my display. Thought they were aptasia and tried aptasia x from red sea on them. Did not kill them.

    Ok, that's pretty cool. Don't think it's Peachia since they're coldwater. There seem to be hundreds of species in Haloclavidae though. There is also Andresiidae, which are also sand anemones. Gonna be difficult to find literature on either.

    thank you @Lord_Blackadder

    OK , I tried getting in there with the big Cannon camera. Its not easy as from the side, due to downward angle the glass distorts the image. From top its not easy to get my head in there to take the picture. Anyway some more pictures.

    I think they are peanut worms - I have one in my tank and all you see is the ring of tentacles. My one never comes out the sand like yours though.

    Where do you think they came from? Local live sand?

    I really do not know, I just found it in my display one day. In the substrate. So I moved it to the DSB.
    Do have it already for a couple of years.
