I need an ID

I was playing with my microscope looking at algae i got from the bottom of my copepod "farm". I saw something and made photos and video of it. On one side it had some sort of tube that was moving left and right like it was searching for food(like an elephant tube) and on the other side it had two rotors that were filtering water(the particles in the water were moving trought it) i think it may be a rotifier but I'm no expert so I hope for your help

That's a stalked rotifer, a harmless filter feeder. It look very similar to Brachionus plicatilis, a rotifer commonly used to feed larval clownfish.

Thanks! I also got one more question. I was doing the same today and found two things. Both on 100x magnification. The first looks like a molt of a triops(at least by the shape) and second one was like a circle with little cilium like things(i think it may be a ciliate but im not sure) the best photos I could get are these ones. Have a clue what could it be?

Those are probably copepod nauplii shells... they molt as they grow.

If you think about it it looks like a corepod. I didnt even knew they were this small.Thanks again
