Umi Blue Xenia
Extremely unique species of xenia, so much so that I gave it a name to set it apart from other so-called blue xenia (usually a Cespitularia sp), this is a true xenia species in that the polyps form a crown on top of a stalk. They do not pulse but are extremely blue which is even more visible under natural daylight. This species is slower growing compared to the red sea xenia. Lastly I caught a cleaner shrimp eating this coral, so if there are cleaner shrimp in your tank keep a close eye on them.
See this one is so limited and rare that "he gave it a name" thats the stupid stuff people are talking about !
