I am not sure what they are but I have them also. I have not experienced anything bad from them.

Spaghetti worms....beneficial.

those look like vermitid snails...
I always find the snaily part and cut/pluck them out. Ive heard they can sting/stun corals.

if they're spaghettis they hunt and peck for food. if its vermetid (snot monsters in my house) they shoot little snot lines out.
