Spaghetti worm how big do these get?

spaghetti worm refers to a group of species of annelid worms. there's a bunch of different species, some of which can get large-ish. The ones that end up in aquariums usually remain quite small. regardless they are harmless critters that basically eat poop and bacteria on the sand around themselves. I think they're kinda pretty myself.
