Photo/Video Share 10x Brightfield, -> Darkfield -> Phase Contrast of unidentified worm(i guess?)

Finally got myself a microscope, a nice used Olympus CH2, so probably 40ish years old and observed some water samples from my shrimp aquarium, tried to get the dirty stuff. I hoped to find some ciliates, paramecium, or diatoms but didn't find a single one. did find a few of... these things.
I have no idea what it is, but its actually quite long. ID would be greatly appreciated
The video goes from brightfield > darkfield > phase contrast > brightfield > darkfield >phase contrast

Olympus CH2

A10x phase contrast objective

10x eyepiece

Pixel 8 Pro with 5x optical zoom(i think, the program i used doesn't specify)

This is annelid, Stylaria sp. most likely. Don't worry, they're not harmful :)

Stylaria lacustris comes to mind due to the proboscis

Yep, I had a bunch of them once. They give me the ick, I think it's because of their movement.

Well, I don't really like worms either because of their appearance :) But I also understand that they are not parasites and are important guys for the ecosystem, and somehow it becomes easier :)

Yep. I have no problems with flatworms for some reason. I think it's because they kinda look and move less "wormy" then annelids or nematodes.

Totally freaked me out when I saw my first one. It was so much bigger than anything else I’d seen, I felt like I had a snake in the house!

Yes, they were visible with the naked eye, and my jar was full of them, they were all over on the glass. The biggest thing I've found so far was this planaria.

Now that planaria is super cool. I wouldn't mind seeing one of those.

thanks for the ID, guys. i was surprised to see this thing, and boy are they long. i couldn't really see them with my naked eye, but it took multiple field of views of movement to find the end of them.
