What are these things on my frag ?

What are these thing growing on this mushroom frag ? The frag has moved to the back but I don’t know what these stringy things are .

Are they hard tubes? If so they are probably vermited snails. A pest you will want to get rid of asap! They damage corals with their slimy webs. I poke them with a needle at the base or rip them off with bone cutters depending on the size.

They were soft when I touched them most of them just rubbed off . One of them opened at night it looked like it had two little worms coming out of it . I’ll try and take a pic of that tonight

It's probably hydroids if they're soft. Get rid of them. They can become invasive.
