I think (and I could be wrong) that it is a normal flatworm. I had some of those about 2 years ago and they were mostly on the glass and never reproduced like the solid rust colored ones. They were clear with the rust colored dot and very tiny rust colored "freckles". That and it looks like it has a forked tail. I believe the AEFW are oval. Those are the key things I saw in your pics.
Also, are you sure about the starfish? They came on several of my frags from different swappers.
