Help identifying organism found on glass (video)

[sim2142]

Hi guys, I’m new to the forum and forums in general so I hope uploading the videos through Imgur work this time

I am in the process of cycling my first saltwater tank and was curious about algae growth on walls of the tank.

While using a microscope attachment for my phone to view the algae growth i noticed even smaller oval shaped things much smaller than the algae moving around on the glass

They apear as barely visible white dots on the glass to the naked eye and when I use a different microscope (which I can’t take pictures through) they seem to be pear shaped with a single dark dot in the center of their bodies.

Any help would be appreciated, thanks guys.

Could it be copepods?

I believe I had/have them in my aquarium. Made a photo of them before when I tried to identidy the red algea on my glass.

Picture from wikipedia:

Thanks for the reply, thought it might be copepods until I managed to get a picture with a copepod next to them.

I circled them in red for scale (they are the little white dots).

They seem to travel in small circles and flick/jump away from the copepod when it goes near them. Maybe copepod larvae?

That was very small

Now I got curious myself of what it can be. Let see if somebody else on the forum are able to identify it.
