SOme sort of invert

Hey guys hope you can help me ID something based off a description. ITs very hard to snap a picture because of how small it is.

In the middle of an acan colony There are multiple ( somewhere from like 6-10) small narrow tubes that are brown in color. Each tube has what looks like 2 small antenna popping out of them that are an inch or 2 in length and very fine.

I am assuming some sort of filter feeding worm thats prob not a threat to the system. If anyone can point me in the right direction I will be able to ID it with picture comparisons.

 

Vermetid Snails and for future references here's a great link to some hitched hiker worms.

lol min late

 

It kind of looks like the spionid Worm picture they harmless?

 

Generally harmless (won't kill or "sting" anything) but they can irritate your corals and affect their growth rates by keeping them closed up. They are actually pretty good filter feeders and will help clean debris floating around in your water. I have a bunch in my tank and don't worry about them unless they start bothering any corals.

 

k thanks everyone for the help
