Flatwarms or black pugs?!

[wesamazmy]

Good day for all,

Please help me to ID these, today I found theses very small bugs on my Zoanthid blugs, they are black and very small and moving a little bit fast and looks black and maybe not, I noticed them only becouse my new plugs still white but no any other signs for them!

Hard to take clear pictures

If they are all that small and stay small, I doubt they are flat worms.

I was able to take this video, it's look like flatworm in the video but the size is very small

The video is too big

Didn't the pugs drown when you put them in the tank? Sorry couldn't help myself when I saw the title.

I saw it too late, wasn't able to fix it
