Microscopic things swimming in my bettas tank

[Nickyt610]

My beta passed away and I noticed these tiny little things floating in the tank and they are everywhere! Can anyone identify what they are?

No idea. What do they look like to the naked eye?

Hi and welcome to the forum

We're going to need some better pictures and maybe a short video. Otherwise take some to a high school/ university biology department and see if they can identify them for you.
