Tube worm, polyp or anemone?

[jimv]

I can't get a good pic but I have little groups of these tube worm or polyp or anemone looking things cropping up in the rocks. They are really small and would like to leave them unless they are anemones.

aiptasia, common pest in the reef aquarium. Lots of remedies to remove directly but the only one that works long term in my experience is a real peppermint shrimp that eats aipt.

They look more like Colonial Hydroids to me. While these are considered to be a pest, the location of them in a tank plays a big role. If you happen to find them under your rocks I wouldn't worry about them too much, but if they're sitting on some prime real estate within your tank you might have to take action.

I believe there Nausithoe sp. (Jelly fish). Google that and see if it looks like them, I have them in my tank, people think these are hydroids form the pick but a quick google will probably tell you.
