Small "bugs" on my LPS/Softies

[reptireef]

Ever since I've gotten a macro lens I've noticed these small bugs(?) on my LPS and shrooms when taking photos. I have no idea what they could be but they do move around and I would have to guess there's probably tens of thousands throughout my coral collection. They appear on nearly everything. For example, gonis, shrooms, chalice, acans, etc. I do not notice them on my acros although I have recently erradicated some flatworms on my sps and have had flatworms on my LPS before but havent had that happen in a year probably.

Any help identifying/treating would be appreciated, here's some not so great/very zoomed in photos I just took.

Are those bugs? Do they move at all? Those may just be concentrations of zooxanthellae in the tissue.

I can see them moving when holding the camera still, they always appear on the base tissue rather than tentacles, and also come and go depending on the coral.
