Looks like Litonotus Fasciola but I have doubts

[Hoolf]

Hello!

I set a petri dish near my other microbe cultures with filtered tap water and active yeast to serve as a reservoir from which to feed the cultures using an eye dropper. On a whim I took a couple drops and put them on a well slide with cover slip and discovered these little wigglers:

They could have migrated from one of the other microbe cultures. My first impression was that they are Litonotus Fasciola but since they move about so quickly I am not entirely sure.

I used a cell phone adapter to record them using my trinocular Swift 380T compound microscope with the 100x Plan objective and 10x eyepiece. They are very fast and therefore hard to keep both in focus and in the viewing frame. Due to their rapid movements I could not acquire either a picture or video at a higher magnification.

Anyone every seen critters like these before?

Thanks in advance,

Steve Wolfrom

It's a Spathidium, but which one ???

As WWWW says, it is a spathidiid (but not necessarily in genus Spathidium). Magnification and resolution are too low for identification to genus level.
