What are those micro-organisms?

[guntank0079]

I recently just set up a planted tank...
I intented to create a shrimp tank with low-light requirement in the first place, and I put in mostly low-light required plants.
Subtrates were placed.
Plants relocated for better view arrangment.
Nutrients were added before I put in any shrimp.
2 sponge filters were used in the 29-gallon tank...

After 4 weeks of plant settlement, the tank had been crystal clear.
Some algea grew and I added six Red Cherry Shrimps in.
The shrimps were handling the algea so good that within 3 days, most of the algea were cleared.

On the 6th week, on the interior glass surface near the subtrates, some really tiny white spots appeared.
They were really tiny; I had to really focused to see their movements.
At first, I thought the Cherry Shrimps will handle them; but they didn't.

It's been a week now, and more white spots appears.
They move mainly on the glass surface.
They are 1/3 of the size of the newly hatched brime shimp.
(That's why I have to focus so hard to see them; but still, I really couldn't tell their real shapes.)

There are two types of them:
1.) Some of them look like with a head, short-bodied and a shrimp-alike tail with 2 bright spots at the end. They walk or dodged on the glass surface.
And there are hundreds of those.
(I have already learned that Cherry Shrimps carry the eggs around which I don't think they are their babies, as I haven't seen any Cherry Shrimp carrying egg.)
(With their 2 bright spots at the end, that's how I can tell they have a shrimp-like tails.)
2.) some of them are thread-like, crawl/move slowly on the glass surface.
There are only a few of them, when compared to the first kind.

Unlike brime shrimps, those micro-organisms stay in their tiny size.

Did those "aliens" appear in your tank too?
What are they?
And why did the Cherry Shrimps leave them alone?

To be honest, maybe they are in the subtrates all over the tank; but I can't see them unless they are moving along the glass surface.

Do I need to remove them? How?

Please advise!
Thanks!

Thank you for the info!

They are exactly what I am looking for.
(And I misunderstood the egg bags of the cyclops were the tails... .)

Thanks again!
