This one is growing on an empty hermit shell. (see attached pic) There are a few more on my rocks. It's pretty small, maybe 1/8 inch, certainly less than 1/4 inch. Some sort of tube worm???

I have a rock that used to be a colony of Green Mushrooms. It has since been taken over by murderous pesky villains who have overstayed their welcome and need to be irradiated. The tube worm has stayed through the whole ordeal and I would like to save it. I plan to remove the rock in full and...

For months now I've been watching what appears to be some type of tube worm living inside my torch coral. It looks like a small white opening in the center, and has 1 (now 2?) long white spindly fan that it claws the water column with. What is it? Is it harmful?

I found this today in a new mushroom rock that i got from my lfs. Not sure if its good or bad. I would like to know a name or species if possible. It has a crown that comes out of the tube but i can't get a pic of it. Thanks for the help

On my glass there are tiny black tube worms. They have the width of an eyelash and they are no more than 1/8" in length. They have little white "mouths" coming out of the black "tubes". There are around three on every square inch of my glass. I think that they are probably filter feeders...

I will be setting up an invert tank with feather dusters and coco worms as a focus. I also want shrimp, snails, nudibranches, and anenomies. My question is compatability. What can I have of the above that will not prey upon each other? I will have swimmers, but only as allowed by the above...

:help: Today we noticed a group of tubes coming up from the sand. The have two little tentacles that pop out and feel around, then go back inside when something disrupts them. We've had the same rock for about two years, and have not added anything new to the tank, so I'm not sure where they...

I noticed these growing in my tank the other day and was curious. Are they OK., or should I remove them? (The little green things, not the plate.)
