Salt Dreams Posted March 30, 2010 Share Posted March 30, 2010 Can anyone tell me what this is...I seen three of them in a rock and one stretches out his worm like tongue or tentacle thingy and tastes my acan. The other two licks the rocks. Are they good or bad Please advise its the best pics I have since they usually only come out at night...

chrisfowler99 Posted March 30, 2010 Share Posted March 30, 2010 It's really hard to tell in those pictures. Are they flat on the rocks or do they stick out? My current guess is feather duster worms, but if they're flat on the rock (or moving) it's not that. Quote Link to comment Share on other sites More sharing options...
Viet-tin Posted March 30, 2010 Share Posted March 30, 2010 does it have stripes? Might be a peanut worm. Quote Link to comment Share on other sites More sharing options...
+o0zarkawater Posted March 30, 2010 Share Posted March 30, 2010 If it is just one or two very thin kinda clear 'tentacles' that wave about, then its most likely a spionid worm. Quote Link to comment Share on other sites More sharing options...
Salt Dreams Posted March 30, 2010 Author Share Posted March 30, 2010 they stretch and reach places that I am amazed about they are kinds clear and they never show the whole body when I try to take the pic they retract back into the rock Quote Link to comment Share on other sites More sharing options...
Salt Dreams Posted March 30, 2010 Author Share Posted March 30, 2010 No noticeable stripes Quote Link to comment Share on other sites More sharing options...
+o0zarkawater Posted March 30, 2010 Share Posted March 30, 2010 Does the white part you circled stay put, like a shell kind of? Or does that part move as well? Quote Link to comment Share on other sites More sharing options...
+Lamont Posted March 30, 2010 Share Posted March 30, 2010 looks like a peanut worm. but they dont like any light. when you shine light on it does it stay put or retract as fast as possible? Quote Link to comment Share on other sites More sharing options...
Timfish Posted March 30, 2010 Share Posted March 30, 2010 If it is just one or two very thin kinda clear 'tentacles' that wave about, then its most likely a spionid worm. spionid worm gets my vote too, harmless unless you're a small 'pod of some kind.

Salt Dreams Posted March 30, 2010 Author Share Posted March 30, 2010 No the worm moves when I shine light on it. I noticed the worms in my tank that look like feather dusters but these are different. It looks like the tip has like suction pulling stuff off of my rocks! Creepy looking Quote Link to comment Share on other sites More sharing options...

Zarathustra2 Posted March 30, 2010 Share Posted March 30, 2010 Digitated Hydroid. http://www.austinreefclub.com/links/goto/6-xtalreef/ DIGITATE HYDROIDS Digitate hydroids spread quickly and sting anything they touch, making them nasty to have in your reef tank. Too bad as it is cool to watch them bob up and down as they stretch out from the rock. I couldn't find a good pic... soooo... enjoy my drawing. LOL. They are white hairlike critters with a bulbous tip which will mostly come out at night. Sorry for the drawing. ___ I don't think they are horrible but they are stingers so worth getting out. The toothbrush at the end of a siphon trick works on them (like just about everything else.) I have some in my cryptic fuge and don't mind them there as they work as scavengers in thier area.

luckylou Posted March 30, 2010 Share Posted March 30, 2010 in my opinion it looks to thick to be a Digitated Hydroid. Quote Link to comment Share on other sites More sharing options...
Zarathustra2 Posted March 30, 2010 Share Posted March 30, 2010 Looks just like some that I have in my tank. Quote Link to comment Share on other sites More sharing options...
+o0zarkawater Posted March 30, 2010 Share Posted March 30, 2010 I don't think its a digitated hydroid. They are very thin and clear. I've never been able to get a shot of one, since they are so small/thin. I have quite a few in my tank. I don't think they have any sort of larger body, just the very thin arm like part that comes out. Unless what I have aren't DH. The only place I've seen them is on that xtal reef. And his drawing looks very close to the things I have. Quote Link to comment Share on other sites More sharing options...
luckylou Posted March 30, 2010 Share Posted March 30, 2010 There is a good pic of a digitated hydroid on melevs reef "Identify that critter/Worms, Starfish & Cucumbers" section. Quote Link to comment Share on other sites More sharing options...
+o0zarkawater Posted March 30, 2010 Share Posted March 30, 2010 There is a good pic of a digitated hydroid on melevs reef "Identify that critter/Worms, Starfish & Cucumbers" section. Yeah, I know what they look like. I've never seen any sort of thicker tube like body, like Salt Dreams has in his pictures though. Quote Link to comment Share on other sites More sharing options...
Salt Dreams Posted March 30, 2010 Author Share Posted March 30, 2010 Ok after review I think it is the spionid worm...the digitate worm has legs on the tentacle with a wider tip...mines does not... the peanut worm has stripes mines does not although the movement is very similar he is a different color as well...if you look at pic 1 there are 3 of them in different areas which makes me wonder if it is the spionid since they all have one visible tentacle? So far though that is the closest suggestion to what I see in my tank with the Peanut worm being a very close second place. Quote Link to comment Share on other sites More sharing options...
Salt Dreams Posted March 30, 2010 Author Share Posted March 30, 2010 Just kidding... I went to the Melev's site and now it looks more like a peanut worm especially his picture and description... either way it is reef safe but i the peanut worm doesnt cause sand problems so I want to believe it is a peanut worm final answer Quote Link to comment Share on other sites More sharing options...
luckylou Posted March 31, 2010 Share Posted March 31, 2010 I Found some in my tank last week also and did not see any stripes at first untill one night i was looking at my tank with a led flashlight and seen one i have been watching for a few days fully extended from a rock into the sand bed, and that's the only time i noticed the stripes it normally only stuck out about 3/4 of inch but when i seen it that night it was extended out about 2 inches and only then i could see the stripes.hope this helps.
