pests

[Piazzon12]

Ok, I've got these stationary snail like creatures that sling webs and irritate my corals. These are not vermatids... they're much larger and can grow up to an inch in a white swirrled shell. I spent the day crushing them and supergluing over them, but just can't get rid of them. Any known reef safe predators? These thigs are driving me nuts

Id's say fill the tube with a kalk slurry and just let it sit in there. they wont live through that.

I'm not familiar with these. Anybody know what they are called or have a picture?
