    Hi Guys. Please help
    My zoas were booming at one stage then suddenly started shrinking and disappearing one by one. I have declared war on the asterina starfish and can't find a single one anymore but its still not improving. My other inverts such as leather and mushroom corals and even the bubble tips are growing and multiplying.

    Any help please

    It's difficult to say, I've had some zoa's that flourish while others just slowly disappear over time, in the same tank, very frustrating. If your parameters are all in order and you can't find any predators then it's a bit of a guessing game. Have you had any temperature swings lately?

    What fish do you have? Maybe one of them has taken a liking to zoas

    Two clownfish.
    Temperature swings. Not that I have noticed.
    But I'll monitor it.

    Something else I noticed was these white patches on my leather coral. could it me related? I just blasted it with a baster and sucked out the hole's to see if anything came out. (only tissue)
    could the symptoms be related?
