Type of worm?

[Brian1f1]

Hi, just noticed my sand bed is practically covered in these. They are tiny, maybe a mm. They don’t really look like planaria? I tried to ID using the forum but unsure. Anyone know anything about these?

Can you pull a few out and take a top down photo of them in a container of water?

I’ll try

Forgot I'd been tagged in this - sorry!

I'm not sure from the pics; closer, top-down pics as suggested above may help with an ID. That said, unless these are juvenile specimens, I wouldn't expect these to be harmful.
