There is something on the back wall of my tank. It's either making a white line in a squiggle pattern or it is a white line in a squiggle pattern. If I stetched the line out it whould probably reach about 8 - 10 inches, but it's all in a bunch about 2 inches in diameter. It hardly overlaps itself at all. I see no distinguishing features (like eyes,) and it currently isn't moving. It is very flat and maybe 2 mm wide. It wasn't there this morning, but it's there now. Can anyone help me with what it might be? Also is it trouble for my tank? I'll keep an eye on it to see if it moves at all. It makes a pretty pattern, but I have no idea what it might be and it freaks me out!
