Some kind of worm??

[JustinF]

I have a 55 gallon aquarium about 4 weeks old and the last several days I've seen this thing coming out of my sand. It has been in the same place. It's translucent white and as thick as a couple hair strands...no feathery stuff, just a smooth looking "tentacle." It comes out and "searches"....I've seen it at least an inch, maybe 1.5 inches long. Any idea what it is?

Looks like a brittle star leg. I have dark ones in the rock and white ones in the sand.

Thanks for the feedback. Don't brittle star legs have little spikes coming from them? This is smooth. Also, there is just one that ever comes out and if it gets scared it retracts, but like I said I've seen it about 1.5 inches out. If it really is a brittle star, how big will it get? Will it get 8" or so in diameter like I see in my LFS?

Its not a bristle star its something else, I've been told before but forgot(my apologies )
I have a ton on my LR and some coming from the base of my rocks outta the sand.
They are harmless and they just collect things from the water.
Some type of spaghetti worm?
Sorry this pic isn't so great I'll take a pic later when the lights are on!

I do not know the name either but I have them in my tank. Sometimes I see them coming out from the rock and picking up sand. It is a worm of some sort.

Yeah, they're harmless.
And they're hard as a mutha to find on the interwebs!
At least the sites I have visited, my LFS told me their fine and they haven't effected my 29g, so....
I'll post a pic later, some of mine are like almost 4"

Ok, cool! Thanks everyone. It's kind of neat to watch it come out and search around for food. I'm new at this....I love to sit and watch all the living organisms in my tank, ones that I didn't knowingly put there!

Hold on, I've been misinformed! Those little buggers are DIGITATE HYDROIDS! And I have a ton! Link below¥
