Hmm...red bugs maybe?

Welcome to R2R!

I struggle to spot what you're referring to, I'm sure someone else will. Did you make a sample of the coral or put the whole coral under microscope?

Take a look at these guys. Especially the comment about how they leave a trail of destruction on corals as the move around on them. It's a pretty large family of critters that vary considerably in size:

I'm leaning towards red or black bugs. Can you dip this coral and see what comes off it?

If you are talking about these, then they look like red bugs to me.

I wouldn't rule out ciliates. The only way to verify if it's red bugs or ciliates is to isolate some and inspect them under a microscope. I need to understand what red bugs are doing, if they are acting like ciliates cleaning dead tissue up or actually damaging the tissue. Ciliates are believed to be clearing dead tissue up and are most associated with "brown jelly disease". Acropora can develop BJD as LPS can.

Hi
Did you find any treatment for this pest?
I take some pics with microscope and put a ruler to show size of pests. The rulers unit is 1/10 mm.
They are much smaller than AEFW.
