Jan, very nice photos, I like especially the 3rd from above.

And you've already written what it is :) : your specimen belongs to the flatworms, or Platyhelminthes (there's posh), more specific one of the free living "Turbellaria".

Looking at #3, it looks like he has recently eaten some diatoms?

That are not diatoms but it's a part of his eating system where his food goes true.

Ah, now I see how it works. He must use that to scrape the surface for things growing on it.

I didn't see it the first time. This is another worm of the same kind.

Jan, these two last photos are especially nice!
This worm has a telescopic tongue !!
Actually it's not working like a 'tongue', it's called a pharynx and works more like an extendable tube the animal uses to suck in or gobble up its prey or other food items. Mostly, the pharynx is situated more to the midst of the body, on the ventral side. This pharynx is the only opening of the animal's intestine ( so called gastrovascular system), there's no mouth at the head or an anus at the other end.

Look, here is a video that shows the pharynx of a turbellar very nicely:
