Help me identify this critter

[HashHunter]

Hi, this is my first post and my first reef tank. Its been running for 3 weeks and all is good and well. I found some interesting critter living in my rock. I've been unable to identify ot on my own but maybe some wiser person might be able to help. 

 

What I know about it's behaviour:

 

It looks like it hides by covering itself with a stoney looking plug. It has one long feeler that seems to just sway in the water column. Not much more. Thanks for your help!😁

Not sure what it is, but welcome! Looking forward to hearing about your setup. 🙂

Thanks. This is very helpful. unfortunately I haven't seen it outside of it's little burrow. I tried. to lure it out but to no avail. Ill wait and see when it outgrows it's current hiding place.

Looks like a Vermatid Snail, large version. They feed by extending a sticky thread, catching detritus, phytoplankton, and 'pods. Their threads can irritate corals and they can spread fairly easily. Some people freak when they show up in the tank, but I for one love biodiversity so I leave them alone.

I would say vermatid snail as well. I have a few that poke up here and there. I generally seal the ends with super glue cause they bother my sps 😅

Thank you so much for answering. I'll keep my eye on it. I don't have any coral or fish in the tank so at the moment I don't think it poses a big threat.
