I think this is a Coleps species. It has, as far as I can see, three thorns on the back side and 3 or four longer cilii. The pattern seen by other Coleps' is only visible sometimes, close to the edge of the ciliate.

Re: Coleps
Another lovely video. 
It is in Colepidae (Coleps in the traditional sense). However, identification to genus now requires a close view of the calcified armour that covers these little guys. A helpful key is available here: https://pubmed.ncbi.nlm.nih.gov/18460156/ At least one more genus has been added, since then: https://link.springer.com/article/10.10 ... 009-0317-0

Re: Coleps
Thank you Bruce.
I have seen lots of Coleps before and I always saw the 'blocked' armour, even at low maginfications. Impossible to not seeing it. In this sample however, I found two, the one shown in the video and another one, in which I could not see the armour. I don't know why. I still have more water from the same pond in a can, so I can try to find more, hopefully even one with visible armour.
