Hitchhiker on the rock

[Brokken]

There is something on my rocks that casts out a little cone of mucus out into the water column and apparently waits for it to catch floating bits of food and then reels it in. A friend of mine has one in his tank, but he doesn't know what it's called either. Sorry. No pictures.

Sounds kinda like a vermetid worm. Do they usually cast their mucus nets when there's stuff in the water column and then reel up the nets like fishermen?

 

Here's a close up of one eating:
