Thanks for the response. It doesn't really look like any of the pictures or descriptions I was able to find. It kinda looks like an earthworm, albeit a small one. It was/is about an inch long or so.
I asked my
lfs what they thought and showed them the picture and was told it might be planaria, but it doesn't look like those either. I'm still confused and concerned about it. I will definitely be pulling it out next time I see it though.
If anyone else has any thoughts about it please don't hesitate.
