Small worms growing on my live rock

Can anyone tell me what these small worms are on my live rock and if they are detrimental to my aquarium? They have been in there for about 6 months and my fish are all incredibly healthy so they don't seem to be causing a problem. Any help would be greatly appreciated.

They are a kind of snail. I can’t remember what they are called. They won’t hurt anything but those shells are sharp so watch your fingers.

mine too. Tanks been up and running for years and they’ve never caused a problem. Sometimes you will see what looks like spiderwebs. That is from them. They are trying to catch food with them.
