I see where you are coming from, Charles. There may be some sort of link given that so many have treated for RB's and then found AEFW's (I did). That's not to say it has to happen this way (at this point, it is difficult to speak in absoultes, as one person may experience something different from another), but if we better understood the relationship, we could start to rule out a few possibilities or find another good theory to start trying to prove or disprove... One intersting observation I've made is that none of my mille's were attacked by AEFW's (despite mille's being one of their favorites from most other accounts), but they weren't attacked by RB's, either. My tenius' was the first to show signs of RB's, but weren't attacked by AEFW's, either. Many of my other corals that had RB's also got AEFW's, where many that were attacked by RB's, were also attacked by AEFW's (valida's, nana's, cerealis, efflo, etc.). Not sure where that puts this response in the argument, but...
