Just a quick question, if the Blue Cespitularia is so rare, why do the wholesalers sell them off for $15-$20 a rock? I was given a piece by some friends who work at the wholesalers. Not that great.
They look similar to xenia, besides the fact that mine don't pulse. I'm pretty sure that the other Blue Cespitularia's don't pulse either. They just move with the current and look pretty, iguess.
The only blue xenia i can think of that pulse are the African Blues, which don't look real blue at all. They look similar to the red sea, its just the growth pattern and the color is slightly different. Under certain lighting, the tips can look slightly blue, but the main body and polyps aren't that blue.
