What is the mouth in the center of the wellso? popped up yesterday. I'm not worried about it, I'm just curious what it is... Anyways, here is a photo of it.

Well, that is a bi directional opening so either it is ingesting or expelling. There are times that you can see a redish brown plume being expelled.
