Tiny moving black dots

[dr_vinnie_boombatz]

Just noticed these after I put in UV. They do move around... What are they?? I remove all plugs and dip. Coral are all very happy and open. They are extremely small and this is the only spot I see them (had this coral for months). Thank you

Could be ostracods..
Look-a-like ~0.25 in the video

That does look very similar! So they're good CUC, whew. Thank you!

Looks to be confirmed with microscope. Thanks again @Shon!
