I would say, in my experience, that my corals did MUCH better without the red bugs. RB's didn't kill them, didn't seem to affect a few varieties ... but I still feel, having treated, that the corals were visibly `better' after.
While they might not kill an Acropora [and there might be multiple species of bugs we're talking about] ... I still would tend to think that they're requiring the Acropora to expend some energy dealing with them.
