Help identifying worms

[Davem24]

Hi All,

A month ago I got a handful of sps frags to test stability of my tank. They did great and showed good growth up until last week I lost one to RTN. Then 2 days ago a second. This morning I saw the tips of one showing RTN signs so I quickly dipped it in coral rx. I found these guys on the frag plug. I suspect they're eating the tissue causing RTN.

Can anyone identify? Sorry the pictures about the best I can do.

Thanks!

I'm old, but it looks like a couple of types of flatworms to me

Ya . I know I have some rust brown flatworms but those aren't of a concern.
