BPM,
Thanks for the closeup. I think you have a female Wennerae there. It has the meral spot and it has the typical coloration on the clubs. The fact that it came out of Florida live rock makes me think so even more. BTW...here's a cool fact about Wennerae. They change colors depending on what they think will be most beneficial to them. If you change the spectrum on your lighting, after the next molt, it will likely change colors.
Abissus,
BPM told you how he got his which is a good way....free.
There are other ways. Have your LFS contact his suppliers for a special order (which tends to be expensive). There are several online vendors who sell them as well...swf, liveaquaria, fishsupply, and tpaquarium.
