As I walked by tank this morning I noticed what I think may be large flatworms in my corner overflow. I've never seen these in my tank before, probably because of my wrasse, but is it something that I should be concerned about? It is basically sand colored with darker dots on it. It also has a raised ridge down the middle with other ridges branching off, it honestly looks like a dead leaf. The biggest one I can see is about 2 inches long. From googling the closest I can find is a polyclad flatworm, which will eat my snails, which isn't a big deal to me. As long as it won't eat any of my corals then I don't mind.
I can't easily get down into the overflow to remove it or poke it to see if it moves. Here is a picture, please ignore all of the spirorbid worms on the glass.
