This is one of Reefer on a Budget's (AKA ROAB, AKA Alex) most sought after corals.  I first saw this coral in 2004 or 2005 in James Lee's old shop, A Reef Aquascene.  It was a jawdropper, and everyone wanted a frag.  Unfortunately for us, he was just holding the coral for Alex.  Eventually, a few frags were distributed.  The mother colony was eventually lost. 

It has been difficult to find, even in the Bay Area where it was first traded.  In fact I had to travel to Southern California to get it.   Many moons before it became famous, Alex traded or gave a frag to on of his fellow Mustang aficianados, Garrett.  Garret and had been friends for some time.  This coral came up during a conversation, and the rest is history.
