Well, since this thread was revived from the archives, I guess I'll add my latest attempt at dealing with these buggers.
I received a coral from a LFS and dipped it in CoralRx as I treat all new corals. I noticed the tell-tale signs of circular bite marks on the coral, so I made sure to inspect the coral well. Sure enough, there was ONE AEFW. I went to send an email to the LFS to inform them and grab my camera...but by the time I got back, the AEFW was a ball of dissolved goo at the bottom of the cup. Thought the ordeal was over. (I returned the coral to the LFS).
A week later, I noticed an Acro in QT looking a bit rough, so I pulled it out. Sure enough, ONE AEFW. The CoralRx did not dissolve that AEFW, but it definitely killed it. I decided to throw that coral away just in case (could not find any eggs) and I already had a clone of it in another tank.
I pulled all of the Acroporas out of my QT and dipped in CoralRx. Found ONE AEFW on another coral, and two corals that looked suspicious. That AEFW died in the CoralRx, but also did not dissolve. I threw all 3 corals away since I had clones in another tank (and still could not find any eggs).
These are the larger tan-colored AEFW.
So, I found 2 AEFW in the entire QT. I'm planning what I think is a more mild treatment than what I've read elsewhere unless I'm advised otherwise. I'm planning to pull every single Acropora out and dip DAILY in CoralRx for a month. I only have about 20 frags in the QT, so it shouldn't be a huge pain...and CoralRx seems pretty gentle on the corals (except I've always had trouble with the ORA Hawkins...doesn't react well to the dip). Hopefully I can break the life cycle in a week or two...and then have another week or two just to be sure.
Thoughts?
