    6 days - I won't be worried to much about it...
    Some of my Zoa's took more than 6 days before it opened....

    But is that a hermit crab on the right?
    Remember -everytime the hermit walks over the Zoa's it will close again....

    My experence with Zoa's is that they open up quite quickly. Yours does not look sick, so I wouldn't worry about that. What I have found, and I am not sure if this is linked to individual species, but placement makes all the diffs...

    What I mean is; if they are in a high flow area now, move them to quiter flow. IF they are in low lighting, move them to higher lighting. For some reason, this makes all the difference in my tank. Give it try, but make sure to not touch or irritate the zoa's, as this proong them from opening.

    Do you feed your corals? If so, and you have Cyclop-Eeze, mysis etc. just spray some over the zoa. This might also help them open up a bit.

    Good luck.

    zoas are very tuff, and are also like a wife, because they sulk for a very long time, even upto a month.

    I had the same issue once with some buttons, and upon inspection founmd them infested with very small white nudibranchs - have a good look at the zoos and make sure you dont have a nudi problem.

    Do you have any predators in your tank? Wrasses and such?

    i brought some zoas from TK 3wks ago and they are only now open(some still closed), and not at full colour yet. i don't think you nd to stress, they are hardy, but do look for those pesky nudibranch though.

    Tank mates

    2 ocellaris clowns
    1 Lawnmower blenny
    1 mandarin

    Inverts

    2 Red legged hermits (very small)
    1 Zebra Blue legged hermits
    2 Astrea Snails

    I checked for nudi s but didnt see any ... moved them 3 days ago to medium flow and light been there for 4 days now and still nothing

    The only other thing is the hermits, but havent seen them on the zoas (I watch my tank alot) the one in the pic is the closest I have seen them get...

    I only feed Tropic Marine Pro Coral Organic currently, have heard of Cylop eeze but Im not sure if I have seen it

    Thanks for the replies

    Iv'e seen these christmas tree corals for the first time last week-end. They look like kenya tree's but is shaped like a christmas tree. You get them in different colours as well.

    As for the Zoa's. Not to worry. about two moths ago my zoa's closed up and only opened after 2 weeks again. Must have been the change in water parameters as I started dosing more KH and PH buffer after some problems. I'm guessing that the water parameters where they came from was much different from your system and like everybody mentioned, they go through a "Sulking" phase.;)

    Give then another 6 days..

    I have some in my frag tank that have been closed for months now

    And I had a few that were closed for up to a year (I **** you not!!) in my sump, they had coralline grow over them, and when I transferred them to my new tank voila!!!! they opened

    These local Zoas are shatterproof, bulletproof, and in my case, idiot proof

    Try moving higher up toward the light. I find that some color morphs require more light than others

    When last have you checked your KH level. I know that my Zoa's start closing up when my KH reaches 10. I try to keep it at 9 and all is fine!
