Hah! cool...always like finding something a little different.
Must have been somewhat lucky with this batch of live rock..
It was collected straight from the ocean and delivered packed in water...
I've seen another just like it in another tank that got a few larger pieces of the same rock, although I admit I just saw the crown and a tad of the body, then never saw it again.
(or is that that behind side? heh silly cukes)
Thanks so much yet again Fluff, you rock!
