Please come in Tiny black flatworm!

[wesamazmy]

Yesterday I noticed a very tiny black flatworm on my new Zoas blugs on the frag tank, becouse the plugs still white! I am telling this because I didn't notice any bad effects on my corals.
Any one know anything about them and if they eat corals or any like that?

Thank you
