My paranoia comes from a Red Bug or AEFW hitching along with the LPS. I know it is a long shot, but when the acros came out of the display, the AEFW were moving all around the tank (bare glass all over, so I could see them trucking around the glass-not to mention the swimming prowess of red bugs)). I'm just gunshy right now. I've had them all, now, except zoa predators and I have been QT'ing sps for at least a year now (just not necessarily for the correct things until lately-didn't know what all was out there to eat my livestock)...
