I am suspected some red bugs too but I found no red/orange spots. Shouldn't they be quite visible?
How long have you had it?
If recently acquired did you dip or treat it with anything like Coral rx?
Do you have any other SPS that are having the same issues?
What are your params like?
To the naked eye NO. But at the level of macro your pics are at you WOULD be able to see them quite clearly.
leave it alone
