This evening while feeding I was observing my tank and happended to look at one of my snails... when I noticed what looks like a small whitish feather duster type thing on the shell. It was grabbing at small particles in the water. Any idea of what it is? I am guessing that it is harmless but wanted to make sure. Video was done with my phone so not the best for detail.
