Thanks guys! It definitely looks like the poop in the picture from the article so Im pretty sure thats what it was.

Noticed small worm like things on my snail and looked to be coming from underneath shell as well. When i tried to grab one with tweezers most of them floated away. The only research I could find was it could be leeches and I am no sure what to do if it is because I have other fish and invertebrates in my tank as well. Any ideas what these are and if they need to be removed or not? Thank you.
