i get these in my saltwater tank, but i have never seen it on the glass, only on rocks and the substrate. so it might be different as to what i have. it is cool looking though! hopefully nothing to worry about
it don't look like those worms. i did get another one today on the glass. from what i've found on the net, they look like snail egg trails. also they don't move (like a worm would), they're just there on the glass.
