Rotifers!

Rotifers

It's not a slime mould but since I'm confined to the house I've spent my time upgrading my microscopes with skip dived parts ( this only works if the skip you're diving into is outside an optics laboratory ). 

I found a thriving community of protista in the houseplants so I've started filming them.

Beautiful! The movement of the cilia creates the illusion of rotation. Have you tried dumping in lots of food for them then watching them feed?
