ID Help; Flatworm or Snail

[reefer200]

Hi Reefers,
A few weeks ago I noticed my snails putting a cloudy substance into the water column, so I was hoping to soon see baby snails! Well, this week I noticed these things and thought all was good, but I'm not so sure they are baby snails. Are these bad flatworms???? I've seen two so far on my glass in the morning, or on the sandbed near the glass.

That's a flatworm

+1 flatworm. Most are harmless and good fish food
