Matts,
Fantastic flourecent green on that one!
Spongebob lover,
It's not easy to trace a frag backwards to the original mother colony and owner, but this one was easy. I got my frag from Jon who had the original mother colony. Steve Tyree from Reefarmers has been very good about documenting the linage for the corals that he sells. Take a look at here:

The confusion is that many reefers are calling their corals names that may have originated from a single line of frags from one mother colony. The problem is that many of the corals have close (or the same) similarities in color & morphology. I have found that same echino frags look very different in coloration depending on the lighting conditions. The bottom line is that there are many of the same/similar corals in the ocean that are being harvested and put on the market all the time. This whole coral naming thing is becoming quite the fad....take a look at zoa names!
Anyway, this is too long of an answer to a good question. My philosophy is to have a peaceful/relaxing tank with nice corals based on good husbandry
