    Another pest to look for is Zoa eating spiders. They can be nasty and are very hard to see.

    Better pics would help, your first pic made me think of Zoa pox, but looking at your other zoas i think it would be nutis. It could also be light related, when did you last change your bulbs.

    I am running SeaChem SeaGel and i have some lugols solution. I have heard that dipping corals can stress them even more and lead to troubles?
    What are your thoughts on this?

    i just changed my bulbs a few days ago. I hope it was just them? But i would of thought that i would of seen an improvement over the last few days and not a decline? The old bulbs looked like they were flaking away? Has anyone seen that in a MH bulb?

    This is how I would proceed.

    Take out the most stressed piece

    1. Examine for zoanthid spiders
    2. Zoanthids with pox will have whitish spots on the column and body of the zoanthid. Google imagae of zoanthids pox and you will see what I am referring to.
    3. Examine for sundial snails.
    4. Examine for nudibranchs and eggs.

    Zoanthids can suffer from fungal infections and dips are the best treatment for this IMO.

    If the zoanthids where doing this prior to changing the bulbs this would be not be my first concern.

    aha, i bet they are just getting acclimated to the new light! Thats one thing that would affect every colony in a slightly different way.

    yeah if it were a pest infanstaion that affect all your zoas you would have seen something. Spiders, Nutibranch, Fungal disease or Zoa pox, some Flatworms, these are critters that will damage you colonies. Having them not open fully or at all happens for a couple weeks after lighting changes or new introduction. See if it gets better over the next couple days.
