Hard tube/worm growth on Frogspawn.

[Butterz]

I've tried googling, but can't find anything.

But it apears that what is in this tube eats the stringy mucas of the frogspawn next to this batch. Last night, I watched it eat about an 8 inch string of it.

Now what is this worm?

I have some of those in my tank too, I think they are some kind of snail.

I have those all over my chalice frag plugs. Break them off they are competing for the food your corals want to eat.

I believe the "string" you are referring to is a sort of web that the worm excretes, captures food in it, then pulls it back in to consume the catch.

I have these all over my tank including on my frogspawn and I don't give them a second thought.

they are vermitid snails

and yes they produce the web to catch particles in the water. kinda like a feather duster just with a little less pleasing view.
