Question after transfer to larger tank

[Str8linespeed]

I just moved everything from my smaller tank to a larger tank 6 days ago. The move went great and all my corals and fish seem to be very happy. With one exception, my most established Zoa colony has not opened back up. Almost all of them are showing a little of their color, but not fully opened up. Only 4 are fully open out of about 60. I have a smaller colony with about 15 heads that has opened completely.

So Im curious, any ideas why they have not opened? My water parameters are with in range.

normally it helps to put your parameters, not just state there in range.
but it could also be flow, placement of rock, new lighting. normally when coral dont open up there unhappy about something. i would wait it out and see how it goes.

Thanks for the reply. Sorry here are the parameters.

temp 79.3
salinity 1.026
PH 8.06
ammonia 0
nitrites 0
nitrates 0
phosphates 0
calcium 460
magnesium 1250
KH 9

I do have much brighter lighting. I moved from a Red Sea C130 with power compacts to a Red Sea 250 with 6 T5's. Although, the other Zoa's are at the same level in the water column. I dont believe its flow as they are kind of sheltered. Like you said wait it out.

Only down side is they are attached to a very large rock and there is not a lot of options to place it in another location, if that is the case.

Bump the mg to 1350. And be sure the DEPTH of the tank/lighting distances are pretty similar. Plus ask what's 'upcurrent' of the unhappy zoa. Might run some carbon to settle it down.
