Weird white moving string??

[Bettaguy08]

I just got a Java fern plant for my 10 gallon, then i randomly noticed this moving white string thing that came from it, i only saw one, does anyone know what this is and how I can get rid of it?

probably a detritus worm that came in on the plant. nothing to worry about
