What are these worms?

[BigOunce11]

Hi, these started appearing pretty much as soon as i started my tank and i think they're really ugly. Does anyone know what they are and how to remove them? They seem to like growing right where the soft lps tissue would cover when they grow whuich may be a problem as theyre very sharp and hard shells.
Thanks

Vermetid snails, you can either snap them off at the base with tweezers or glue the opening to their tube shut.

By becoming their biggest predator. Many pests in this hobby have no other solution but to be proactive about removing them manually.
