Found something odd on my heater this morning when I went looking for one of my mystery snails. The snail has been in the spot in the picture since last night, so I'm not sure if the film is from the snail or something else. Any recommendations on what to do about it? The fish don't seemed bothered at all, and tomorrow is my scheduled water change day.
