I guess the fact that more people didn't immediately know what this was means we are doing a better job of keeping and transferring BTAs.
As Dave has said several times, this is a common rose BTA that has bleached for one reason or another. Water temps above 84 degrees is a common reason, as is lack of proper light.
I hope your LFS owner thinks he just got a rare anemone by mistake or luck and didn't pay more than normal RBTA wholesale price for it.
