Problematic Flat Worm?

Somehow accidentally posted this in the wrong forum.

Just got my shipment of clean up crew. As I was checking the bags I saw this guy in the nassarius snails. Looks like a Flat Worm and potentially one I don't even want in the invert QT tank. True?

When in doubt, toss it out.
Looks like a flatworm to me as well.
