ID? Protozoa I Think?

[UFreefer]

These came off with a Bayer dip from some frags I received. One of them sort of shows a fork in the tail at one point but they definitely are not Planaria. They move in a way that seems different than a flatworm. What do you think?

My eyes are not that good anymore, but that does looks like some sort of flatworm to me.

Sorry, been a busy week for me.

I'm not great at microscopic ID's yet - any chance you could get some microscope (or otherwise heavily magnified) pics of one or two?
