Flatworms? ID help

[mdock]

I’m working on resolving the GHA issue and got some new zebra snails to help with that. Haven’t noticed these guys until I got the new snails and a new coral. I counted about 5 of them about 1/4 inch or half a cm long. Are these flatworms? I haven’t dealt with them yet. I have a six line in my other tank though that may have prevented it. Should I get a wrasse for this tank? What is the recommendation? Thank you.

It does look like a flat worm. It is difficult to accurately ID due to the picture.
A 6 line would make quick work of those though.
