Tiny Black bugs ID

[Flax75]

Hello,

2 weeks ago I noticed that tiny creatures (about 1mm length) in my tank and now there is a plenty of it. They live in sand and they mostly appear at night moving quickly even over rocks.
Can you help me identify these organisms?

Sure just not ampripods as look quite large in the blurry picture,I'm just in middle of trying download your video to watch.
It's best to upload video to YouTube then share link as easier for others to help you

What is that!! A R2R guide to common new tank hitchhikers.

One of the greatest things about starting a reef tank is getting your live rock in and admiring all the diversity within it. The rock comes to life different creatures. This is a guide that I, along with a very well known critter identifier @KJ , have put together for the new reefer on what...

Here you go,look at the pods and see if thats them.
Usually where we find the micro fauna is what it eats,so if find on fish then fish parasite ,find on coral then coral pest,find on r9cks sand then algae/detritus eater etc
Not always but good indicator.

Good luck

Thank you very much for your help. I looked closer and I can spot bit curving off the body. I am dosing live phyto and looks like they helping me with dinoflagellates.
