Sorry, so most Xenia I’ve seen is like one thick base with a bunch of polyps, mine is just a ton of thin 1”-2” stalks with one polyp.Not sure what you’re asking based on pic. Can you be more specific with a clearer pic? Definitely a xenia though.
So yours doesn’t have a thick base? I see lots of polyps in that pic you posted.Sorry, so most Xenia I’ve seen is like one thick base with a bunch of polyps, mine is just a ton of thin 1”-2” stalks with one polyp.

You notice the key different, Xenia have one trunk with multiple heads while Anthelia have single head per stalk. Anthelia move with water movement, not pulsing like Xenia. Some of the Anthelia have polyps very similar to Xenia, while others looks more like green star polyps (Pachyclavularia sp).Really think so? The polyps look almost exactly like pom pom
Sorry for the bad quality

@Bryce M.That's def xenia, star polyps don't look or act like that. mine form a thin skin on the rock
I recall reading that these corals have been reclassified many times and some people still call them by the improper name i.e. xenia when it is no longer classified as such. You’re right though, it is anthelia. And many people also refer to them incorrectly as xenia.@Bryce M.
Your coral sound like a Clavularia sp. They grow in mats with polyps extended from there. The problem with common name is that these Genus (Xenia, Anthelia, Clavularia) and Heteroxenia all have somewhat of the same common name, depends on who calling them.
If anybody interested about finding the differences about these corals, all they have to do is search and read about them.
The OP's coral is definitely a coral in the Anthelia genus. I am not certain on the exact species. There are a numbers of species in each of the 4 Genus mention above. I am not good enough to ID them to the species level other than Xenia elongata.
Anthelia can retract their polyp completely into it's stalk if disturbed. Clavularia can partly retracted and formed into a little ball at the end of the stalk, while Xenia cannot retract their polyps at all, only curled up when disturbed. Heteroxenia have dimorphic, two types of polyps, thus named Heteroxenia.
Julian Sprung's book: "CORALS A Quick Reference Guide" published in 1999 mention these corals. Does ot give a lot of information. However, quick search on the internet will give information on these Genus of corals in detail.
oh interesting, I post to educate and learn@Bryce M.
