So I was traveling yesterday and stopped by an LFS. I picked up a few frags; Lokani, Echinata, Desawlii, and unknown (possibly a second Desalwii, possibly a Tenuis). There was AEFW in the system, but didn't seem to be affecting any of the pieces I bought. So they came home with me. I clipped them off the plugs, dipped them in Bayer (5 mL per 250 mL tank water, rinse in tank water well). No AEFW came off, and I didn't see any eggs on the plugs. I chucked them in the QT with the Anthias.
So this is where things get complicated...
I dosed PraziPro to the QT with the Anthias last Tuesday (a week ago), and the treatment should be complete now. I check on the Anthias this morning, and they look rough. They have the "rough scales" appearance. One has some whitish edges on a couple spots on fins. Half of them look a bit Ich-y. So this isn't really the complicated part -
except I just put SPS frags into the QT!!! 
So I think I'm going to move the SPS frags into the display tank, and hope for the best. The tank is just frags right now, so if worst comes to worst, I can remove them for AEFW dips. Le sigh...
