Weird string from base of torch coral

[Anubisxii]

My torch has from time to time had this long white string from the base of the coral extend. I attached some picks anyone got any ideas. It's branching hammer.

Is there a vermetid snails on the skeleton ?

Is the string coming out of a tube? Might be a vermetid snail.

I'll do a close inspection tonight, are those snails a danger to any corals?

They will irritate coral. If there is one you can simply crush it

Some say they inhibit SPS growth. Their little strings can certainly irritate corals.
The population can really explode if you let them. I would crush it asap. Make sure you get the base of it and not just the tube.

And correction. It was my hammer not torch, I was at work when posting this and my head was all over the place
