The name of the true blue xenias are : cespitularia
It is non-pulsing xeniid species.
The cost of a stock can get quite pricey. I've seen 1 stalk for $180.
Very rare, I believe there are a few reefers on here propigating them.
From what I hear it does not grow as fast as the rest of the xeniids.
As for pics, you can type in cespitularia in the search and to see some pics, I posted some but I currently cannot locate the images on my computer.
