Is this a pest on my torch?

[huthain]

So i have 4 torches, one in my tank for 4 weeks the rest for just under 2 weeks. The older one has opened up real nicely and stayed that way for the most part. 2 of the other 3 are fairly open most of the time the third though while it is open its much smaller than the rest usually. I am not sure if its just a smaller torch or something is bothering it. So I inspected it at night and saw these not sure what they are but any cause of concern?

Looks like vermetid snail tubes, remove the torch from the tank, crush the tubes, rinse the torch in a container of tank water outside the tank then return to the tank. Do this to make sure you dont spread eggs in the tank by crushing them inside the tank.
