What are these things??

Hi everyone,

I’m new to the fish keeping hobby, and wanted to get some input as to what these things in my tank could possibly be.
I have a 20gallon planted tank, with two nerites and about 8-10 red cherry shrimp. (Will soon be adding some fish). The tank has been setup/cycling for about 2 months now.
I was just about to do a water change the other day when I noticed some tiny red worm-looking things squiggling through the water!! They make these strange erratic movements but seem to be able to propel themselves through the water pretty well.
I pulled about a dozen of these out of my tank after the water change, and I’m sure I must have missed some.
I’ve attached some photos and videos of the worms, hoping you can help me out as I cannot seem to identify them through pics i’ve found online... they also seem to hide/burry in debris and leaves...

Thanks in advance everyone, for your help!!

Have you checked this website?
The Worms!
They have photos/drawings of any kind of worm or parasite with very specific characterization you might get in your aquarium ;)
