red bugs?

[PL-Reef]

how do you know if you have red bugs? does anyone have pictures that i can compare with.
i have some small black (dark) dots on some of my sps - green slimmer - german blue,orange,purple montipora digita - and a few unknown acros. not sure what they might be.
any help would be great. thanks

They don't attack monti's, by all accounts so far. Below are some pics from when I had them.
