Little Unknown Critters In My Shrimp Tank

[killudead]

I have a 10g tank that has been running for some time but it has been empty, or just a few snails and lights were always off. I recently added a few cherry shrimp about 30 days ago. I have many that are pregnant and some have even given birth at this point. So i have all these little baby shrimps running around.
Anyway, I was looking at the tank and notice this large group of what look like baby snails. About the head of a ball point pen.
But then i see them move real fast, so I know it is not a shrimp.
i have added nothing to the tank except the shrimp grass and flame moss that i received the shrimp.

Now i am not sure what the little critters are, possibly some type of water bug. I doubt they are doing anything to the tank or the shrimp, but i want them gone if possible. Anyone else ever deal with this, or have any suggestions. They are to small to see with the naked eye and I do not have a magnifying glass in the house.
Suggestions and Thanks

Go to poundland and invest in a magnifying glass or use a camera with optical zoom and zoom in on macro mode. Then ID here:

If its a invertebrate then trying to kill them without killing the shrimp will be very difficult.

Post when you do I have caught the aquatic forum bug again.

based on the link i feel like they might be
Freshwater copepods(Cyclops)
or
Ostracods(Seed shrimp).

They must have come in from the last batch of shrimp that i got. The problem at this point, I think it will be almost impossible to get rid of all of them. Just catch as many shrimp and hopefully i get none in the water while catching them.
They are on the back glass and on some rocks i have. Basically where any algae might be.

 

[saltynay]

Well the ostracods and copepods are no worries they just balance out the ecosystem.

 

[killudead]

is there any way i can keep them in check. Maybe a tetra or something that wont eat my baby shrimp.

 

[saltynay]

By not feeding them too much and general steps for reducing the algae growth. Like "pest snails" they will only populate when their is sufficient food available therefore filling a niche in your ecosystem. If you reduce the amount of food available to them then you will reduce the population, if you introduce competition for their food then you will reduce the population, if you add a predator that likes small inverts then you will most likely lose your baby shrimp as well as reducing the population.

If they become a nuisance then its natures way of telling you that you are not providing a well rounded ecosystem.

update:
I took all my shrimp out of the 10 gallon, and put them into a 5 gallon.
I noticed just a few of those critters in my 5 gallon, so I need to hurry up and get all the shrimp back into the 10 gallon and get that running.

the little critters are tough. the resist water with no heat(room temp) (upstate ny winter, mid 60s in the house)
also added a few drops of parasite killer. they lived through that also!!

 

[saltynay]

Increase the water temps to 40<C or decrease the water temps to <5C provided you have taken all you livestock out. That will kill them

so i was finally able to get a magnifying glass.
i tried to get a pic but my camera wont zoom that close. Just show up as black dots.
but they look like this a little

however, I see little antennas in on the front with tons of little legs for swimming.
Also, good to know, they have gray and white stripes on them.
but they do not appear in the link that you posted in this thread

Like this:

If you want to nail it down further look here. 99.9% likely they are harmless critter that will be near impossible to get rid of.
