    I had quite a verity of local Zoa's that where doing very well at some stage.
    Blue as very difficult to get going and had to batches fading away quickly.
    My orange and pick ones are lovely but some has started killing them off one by one.
    Its not eaten by fish. they just start rotting away from one side till it reached the other side of the rock that its hosting on.

    I did try the coral disinfectant prior to placing them in the tank but still dying. pH and calcium levels are fine. Treating my 4 ft tank everyday with 15ml of Reef Fusion 1 and 2 each. Have 2 x 1.2m white and 2 x 1.2m blue T5's. Fish are doing well.

    Any advice?

    Are there any snails on the zoas?

    If you see any of these then you know why they disapearing.

    Thanx guys for the replies.
    Yes I found some of these snails and removed them. I found a big black one today and was shocked when I saw the holes it made. They have serious type drill shaped mouth.
    Water temp is +/- 25,5.
    I have no shop bought zoa's.
    I thought it was probably zoa spiders but couldn't find any.

    Also just bear in mind that our local zoas is probably used to cooler waters and some will adjust while others might not.

    Mine too but some of my local one's also rotted away and i then manage to do a little experiment. I took them out from my DT and put them into my QT tank... dropped the temp to around 18 and over 3 weeks raised the temp to 25deg they came right and survived....so yes i do believe the sudden shock of temp change could lead to some not surviving

    Also, make sure you propagate them properly,
    I noticed if you don't remove them properly they will look fine then start to die off a few days later.

    I also found a spider looking thing sitting in its whole under the Zoa's. The pic of it is not great but it was moving inside. There is also a spider web of sorts always over the Zoa's.

    Web could be from a vermitid worm. Does the web come out of a calcareous tube?

    Yes it does. You are absolutely spot on with that. I Googled it and that's what I see in my tank and in my pic with the Zoas. Thank you! I'm not sure if it has any detrimental effect on the Zoa apart from maybe catch food particles prior it reaching the Zoas.

    They do irritate the zoas, But I don't think they can die from it.

    Those sundial snails are a problem. If you found two then there are most likely more. They kill zoa colonies quick. Got to search all your rocks carefully.
