What Are These Tubes

[carrera mike]

Help. Could someone tell me what these tubes are(Red arrows)?? They put out webs(green arrow) like spiders to catch food. You could see with the first picture that a pellet(yellow arrow) is caught in the web, then within 2 minutes this tube reeled in the web with the pellet.

Thanks!

I forget what they are called but i have 1 in my small tank and a few in my 180g. They are harmless worms and just catch whatever they can in their "webs".

In my 180g, there is one right next to a few acan colonies and even though the web is always on the acans, i have never seen any bad affect and the acans have no reation to it.

YES! I looked Vermetid Snails up in google. Thats exactly what they are! Thanks!

I dont think they're bad either. I had these five for a long time now, and there's not much anoying web. It's more of curiosity for me... What life forms they are. Im just amazed how life adapts.
