    Yesterday, healthy happy pulsing xenia colony. Today bare rock. Any ideas?
    Can't find it, or even bits of it in pumps or sump. I assume it's been eaten last night.

    Livestock
    Perc Clown
    Blue Chromis x 10
    Mandarins x 2
    Bicolour Angel
    Cleaner Schrimps x 2
    Green Starfish
    Cardinals x 4
    Few Snails

    Cant see that any of these guys would have been THAT hungry.

    Any ideas please?

    The small colony was about half the size of a cigarette pack? Sorry, only thing at hand to guess by ( but only one stem connected to the rock ). Maybe around as many as 12 pulsing heads, it's been happy in the tank for about 3-4months.

    Dallas, not sure of name, but here's a pic of the starfish. He's been in the tank for ages.

    Hi there it could be a tiny white star fish(i dont now the technical name)if you do have, get a pair of harlequin shrimps they will chow them, and look out for nudibranch as well

    Thanks for the ID! So he's not the obvious culprit right?

    the problem with the green star fish is that they got to be fed every day,other wise they will attack corals

    Are you sure it hasn't jumped off? Sounds wierd but I often have whole stalks decide to relocate.

    Actually now that i look very closely there are a bunch of very small starfish, white and pink in colour, hard to see on the live rock. Very small but funny - some have only 3 legs, some like 6 or 7. Are these buggers breeding and maybe the cause?

    @Dane - so Xenias do let go of their own accord and try and reposition elsewhere?

    Yes, they loosen their foot just like mushrooms if the conditions are not suitable for them. Low nutrients and low KH would be such unsuitable condition. Especially if there was only one piece connected to the rock. I received a few small rocks with xenia and within the first day, more than half of them moved. Moving means, floating with the current. I found most of them behind the reef. So maybe they are still there.
    Also xenia is not xenia. Some grow like crazy in almsost any conditions and some a very tricky to keep.

    KH for xenia and leathers should be 10 plus!

    Thanks for all the replies. I think I caught the culprit - it was a little brown crab with orange pincers. Only comes out at night but his home was in a crack right where that xenia used to be. And a few chunks missing from a nearby kenya tree too...
    Sorry to say, I had to deal with him with extreme prejudice, and now he sleeps with the fishes.

    If there are chunks missing from a coral, then it could be a fish that's eating them too... I Know angels eat corals... They are particularly fond of softies...
