I have some small white coil looking things with polyps fanning out of them on my hammer coral that appeared to have multiplied in the last days along with a larger purple mass. I searched online and believe they may be vermitid (sp?) Snails or tube worms. Could anyone please confirm? And if they are please advise if these can be scraped off in an iodine dip or best way to remove? My first noticeable pest in my tank and it's bumming me out. Thank you in advance.
