What type of Flatworm is this?

[Steve2020]

Found this little guy on my glass this morning. Removed him and took some photos. Looked at Flatworm identification documentation and can't seem to find a likeness. Luckily not a AEFM. Spent a good 1/2hr looking around my tank and can't find another one. Any ideas on what type it is?

I'm trying to see if I can get an ID too. I'd be ready to call in the national guard if any of the coral have damaged edges.
