    Hi

    Got blue Anthelia (I hope), can anyone confirm or suggest the correct ID? Also, is there any way/use to have the specific specie identified?

    Got them as I believe that they are less toxic and more controllable than Xenia (aka E.H Borneman), but have found some online comments to the contrary now. Any views?

    The blue is very much in the eye of the beholder as it shifts form pinkish hue to a blueish hue, although the columns is blue-purple.

    I got a frag from a friend and its growing like mad. From what I've read, the more light the better. They handle strong flow quite well. I wouldn't place them on my main reef/rock.

    They grow quickly, place them on a separate rock away from the reef. Just my opinion.

    Looks more like Xenia than Anthelia to me. Do the polyps share a common "trunk" or do they all join on a common "mat" on the rock?

    I have them on a small rock in the substrate on a point where my pump streams get together so they are being hammered with flow. Hoping to anchor the sand at that point with their rock.

    They are directly under my 150W MH, 53 cm down/away, on a white sand bed, should be enough?

    Still in two minds about having them, love their movement and colour, but don't want to introduce problems to my tank.

    Focus is LPS, and worried that their toxin with effect it as well?

    They grow from a mat on the rock, but there is one or two trunks that are split. It is extremely dense, and the mat is seldom visible.

    Hmmm, any chance thats african blue cespitularia? Shine a torchlight on it in the dark, and if is sparkles then I'd say thats what it is. AB cespit very seldom has such large polyps tho.

    Polyps open and under moonlight

    Here is a shot with the polyps blown a bit open:

    And under "moon light". Note the polyps are completely contracted. I used my phone's flash, so colours distorted.

    Probably a noob question.
    What is the difference between these and Clavularia?

    Hi

    Sorry for my slow response, a bit snowed under at the moment.

    @Kender, I found this handy page to distinguish the varios (closely related/similar) ones:

    http://www.utahreefs.com/articles/Dichotomous key for soft corals.pdf

    Here is also a good link for Green Star vs Clavularia (Clove)

    Clavularia---Green Star Polyps (GSP), Clove polyps


    The short list is currently:
    Xenia sp.
    African blue cespitularia (True Blue African Xenia)
    Pachyclavularia (green star polyps)
    Clavularia sp.
    Anthelia sp.


    Been looking online and in real life at a few. It does not look like Xenia, not branching (think the one or two stems that are is an exception). African blue is out as it does not sparkel. :(

    Although the "daisy" has a striking similarity (see pick) with some green stars I have seen and the retraction and mat looks similar, I have not seen them in blue anywhere?

    That leaves Clavularia and Anthelia. The typical Clavulatia I have seen, seams to have two separate parts to the stem, and the top part retracts into the bottom. This coral is looks more contractable (than retractable) with a homogeneous stem.

    Then to add to the confusion their is Sarcothelia edmondsoni ( Blue Soft Coral, Sarcothelia edmondsoni ) It is in the Xeniidae family and formally was classified as Anthelia edmondsoni?

    @leslie hempel I think this is the closes and I will treat it as Anthelia for now and keep an eye on it. Love the large waving display and the colours shifts it has.

    I had a rock of what I identified as Anthelia.....looked the same as what you have....

    Never lasted long, just waisted away over a few months for no reason I could pinpoint.

    :(

    Will keep an eye on it. In the week I have had it, some new polyps has appear at the bottom of the colony.

    Weird how one specie (or is it specimen) can become a weed and the other one that looks similar/identical won't grow.

    I am hoping I have something in-between.

    It is wierd.....I read an article somewhere (cant recall) were they class Anthelia as a difficult coral species....I must be honest Ive never seen a very large thriving colony anywhere.....

    My temp moves between 24.5 and 26, hope that is stable enough for it. I have a fairly big chiller for my tank so should not struggle with overheating, but will have to see what Cape Town and the MH light can come up with this summer.

    In terms of their "tuffness", lots of opposing views. Borneman (Aquarium Corals: Selection, Husbandry and Natural History) says that they are easier to keep than Xenia , less toxic and less invasive. Sounded like a great option for a softy. Will see how it goes.

    After an initial growth spurt, it is now slowly wasting away. I had it in full light, high random flow area moved to full light, low random flow, to no avail.

    I also tried feeding it with zoo and phyto planton, still waisting away :(
