No mucus web = not a Vermetid snail?

[CallMeChris]

If a tube does not have a mucus net coming out of it, does that mean it is not a Vermetid snail? When is the best time to see the web? When Feeding I assume. Does time of day matter?

Thanks!

it could be a old/dead tube, feather duster, etc. can you share a picture of it? You would usually see the mucus web during feeding time if it was an active vermetid

It’s not in an easy to photograph area. Any attempts are a blurry mess

There are different types of vermetids. Some don't seem to throw webs...
