That was my incorrect assumption too. I just meant the trend of people posting the condition of the frags they received from RRU. Mine was over a year ago I think, so I don't think it is a sudden recent development.
The parasitic copepods are similar to red bugs but more dorsoventrally flattened, much more camouflaged, and resistant to regular dosages of Interceptor and sometimes Bayer dipping. You can see them best at night with a flashlight, sometimes they have reflective eyes that are easier to spot. They are clear to beige colored, sometimes with a transverse lighter beige to white band across the middle. They seem to prefer tenuis, hoeksemai, tortuosa and other dark blue corals. Sometimes they are on granulosa and other "smooth skinned" acros, but seem to be at lower densities. They are also fast and will run inside the corallites to hide, so they are much harder to detect than red bugs.
I usually quarantine and treat twice with 12x the normal dosing of Interceptor for 6 hours, 2 weeks apart, in addition to Bayer dipping. I've heard the potassium salt dips are more effective, but I had them survive those too.
It is such a hassle that I try to avoid getting corals from anyone but the handful of people that I trust, who I know are aware of them and how to treat for them.
