Spiney clear thing with tentacles???

I have seen these in one of my tanks before and its not a spaghetti worm for sure. I cannot say what exactly it is other than some type of filter feeder.
I do know however that it stays small and is not bothersome to the reef.

 

ya spagetti worms definatley dont have spines, and there tentacles are usually solid green or yellow and thicker than hair

 

Pineapple sponge with a commensal brittle star living within, or something along those lines maybe.

 

nope... they are a little smaller than a pineapple sponge and the hair-like arms dont move.

I have never seen these come up online before anywhere so i am at a loss as to what they are. I just know from keeping them they are not detrimental to a tank.

 

Well, I guess it remains a mystery... good to know it won't harm anything though!

I also forgot to mention that my LR is Timora. Also, the critter has a hole very close to it that it seems to poo out of.... Like it's got one hole for eating and it's detritus comes out of a hole less than 1 cm away. This seems to indicate that it's in the worm family, but I could be wrong.

Any more ideas?
Thanks everyone!

 

you need to get a pic up that would be the best

 

I have tried but my crappy camera doesn't pick it up because it's so clear. I drew a pretty accurate picture posted on the previous page.

 

The problem I keep coming across is the spine thing. Worms for the most part do not have spines. The rest of your description and picture looks very similar to a worm.

Because I am me, I would touch it. And if you can remove and take a picture of it against a backround that will provide contrast that would help.

 

Sorry not trying to hijack the thread but the picture of the star on the left is what I found. What is it?!
