Teeny, Tiny white snail

[threebuoys]

Any idea what kind of snail this is? I'm trying to get a better image, but they are so tiny I've not been able to do much with them.

I'm curious if they will stay this size or get larger. I have some astraea and trochus snails I purchased 9 months ago, otherwise they have to be hitchhikers.

Tiny feather dusters. Not snails at all.

Feather dusters, really? So tiny and they look hard and I can't see any openings sicne they are so small. But they don't seem to move, or not much if they do.

How to Get of Spirorbid Worms Infestation?

Hi all, The amount of spirorbid worms in my tank is out of control. They have completely covered ALL the live rock, the back glass, and it's starting to grow in the sump creating a mess. It started about a month ago and it's significantly ramping up. I've read most of the threads...

Apparently new tanks get them in quite some numbers if feed alot but they filter feeders and often their numbers go down once tank matures more.
I myself got quite a few of them on rocks and back glass and starting in my sump.
I just leaving them be for time being as cant see them do no harm
