    Hi, as per title really....so I have a problem here? The pics show the star cupped over something and then confirms it was over a zoa....now, the colony is healthy and looked like it was growing; over the past week or two it looks like some have gone....none are or were lose hanging and open fine, unless there's a bloody asterina over them.

    So, are these little beggers actually eating them one by one or are they being a fatal pain just by simply cupping over the zoas?
    They dont do this with my green "dragon eye" variety just next door to these and cannot cup over the bigger palys.....anyone able to shed some light? Is this why I've never been able to sustain zoas for a prolonged period of time? Is it Harlequin Shrimp o'clock???

    There was a thread on here a couple of years ago where someone (can't remember who) was loosing zoas to astrena stars.
    Turned out there is a type of astrenas that will and do eat zoas.

    If you mean the bigger "flower" on the left, thats just one of the zoas; you can see the same one in first pic..

    I have had this same issue. I also had an interesting debate with a very experienced reef who suggested they don't eat zoas per se but they eat dying flesh.

    I disagree. The ones I had like a plague were outrageous.

    Some types of asterinas can and do eat zoas. Iv got them in my tank but they don't touch my zoas just eat the adage on the rocks and glass.
