White worms??

Hello, I have/had these white worms in my tanks for a few weeks. I didn't really notice them too much until they numbered ~100 in a 10g tank with my 6 weeks old clowns. Here is a short video of one I saw while videoing my royal gramma larva. Any ideas?
 
I want to get a microscope but I remember seeing somebody on here using their DSLR with some sort of lens adapters instead. Does anybody remember who that was or what he is using?

I can't remember the name off the top of my head but I've seen those at night while looking at my tanks.  I want to say that those are a type of bristle worm, as I've gotten them (bristle worms) in the hundreds in my tanks.

I've seen tiny white worms that I also think are very young bristleworms.  When I look at them with high magnification, they look basically just like bristleworms, but without the coloration.
 
I have a bellows I use with my DLSR that turns just about any normal lens into a pretty powerful macro lens.  You might check it out.  Google "fotodiox bellows canon" or fotodiox bellows nikon", whichever applies to you.

Planaria maybe ? Not quite long as your specimen, but have found white worms in my old rotifer cultures...
 
They are 1-1.5 mm
