MC Wheels Posted December 19, 2014 Share Posted December 19, 2014 I've spent the last few nights reading and looking at pictures and I have not found anything that looks like this guy. I've tied to suck it out but it is holding onto the rock too well. I cant dip it out because the corals in the LR are too awkward to move around too much. So, I post a picture of critter in place. I have many pictures, and videos of it.. there are several In the tank.. maybe 1mm wide and several inches long .. one lives under my zoe colony the other lives at the base of my hammer.. I don't see any negative effects from them but if they are the sort that if you don't act early, later they are a problem I would like to know about it now. any help? Please ask questions if you need a detail to help diagnose. Link to comment
amphipod Posted December 29, 2014 Share Posted December 29, 2014 Looks like a brittle stars arm. But it could be a worm. Can you see multiple in one hole? Link to comment
jamescstein Posted December 31, 2014 Share Posted December 31, 2014 Looks like a serpent star leg to me too. Link to comment
MC Wheels Posted January 4, 2015 Author Share Posted January 4, 2015 I can see several of these, maybe three, all with in a few inches of eachother. the rock its in is very porous, and I never see two of these coming from the same hole and I've never see if they connect to a central body.. meaning I've never seen the other end of it. in ether case, is this a bad thing or just ignore it?

amphipod Posted January 4, 2015 Share Posted January 4, 2015 Its probably harmless but keep us informed of what you see. Link to comment
MC Wheels Posted January 4, 2015 Author Share Posted January 4, 2015 well, so far it has not harmed either of the corals which it is usually seen around the base of. If its a star then it should have no ill effects and the pictures I've seen of stars do look like the arms I've seen thus far. Interesting I only see the arms though. I've not read about brittle stars keeping to the inside of one coral, never moving from that spot, and never emerging except for a single tentacle. thank you very much for your replies.

ajmckay Posted January 4, 2015 Share Posted January 4, 2015 Its a peanut worm. Harmless rock boring worm. Link to comment
amphipod Posted January 4, 2015 Share Posted January 4, 2015 But peanut worms are rounded at the tail, not tapering like his. Link to comment
ajmckay Posted January 4, 2015 Share Posted January 4, 2015 But peanut worms are rounded at the tail, not tapering like his. Pic isn't good enough to really tell... the op will have to ultimately I'd the critter, but to me it looks like a peanut worm... They are able to extend quite a bit and as a result they taper down.

ndrobey Posted January 4, 2015 Share Posted January 4, 2015 Perhaps it is nocturnal. Try waiting until the lights are out for a couple of hours, then surprise it by turning them on. If it is out and about, you can get a better look at it. Link to comment
amphipod Posted January 4, 2015 Share Posted January 4, 2015 Usually I just get a really dim flashlight and peer at nocturnals. Link to comment
Dr.Brain Coral Posted January 4, 2015 Share Posted January 4, 2015 I am willing to bet money that that is a serpent star arm Link to comment
amphipod Posted January 5, 2015 Share Posted January 5, 2015 We need to see what is found, but your probably right. Link to comment
Thomas898 Posted January 5, 2015 Share Posted January 5, 2015 Definitely leaning towards serpent star arm. I have heaps in my live rock, two haven't moved in 6 months and I only see the tiny arms.. Try and feed it a piece meaty food like you give to your corals and see if it accepts them. You will know immediately whether it is a serpent star based on the way it will grab the food.
