White Flatworm?

    Last week we noticed whitish flatworms slithering on the glass of our frag tank that contains just sand, rock, snails, urchin and a couple frags from the fragging workshop. Wondering what they are and if people have had any negative experiences with them. Also wonder where they came from, which I know is impossible to know. There are also some very tiny worms that under the microscope look like mini polychaete worms, plus a big gang of running and swimming tiny shrimp which is weird because the rock has been in there for a few months and it's been at least four months since my lone peppermint shrimp went missing in the DT.
    Here is the best pic we could get of magnified flatworm:

  2. My understanding is the white ones are harmless and will eventually disappear. Also, Six Line Wrasses love them.

    That's what I found as well. Red = bad though.

    Harmless from my experience. This one was a decent size that came and went.

    Is that a nassarius snail next to it?

    I'm guessing that's gotta be a Cerith Snail

    Dwarf Cerith. Baby there at ~1/8".
