What is wrong with my Zoas?

[ReefGeek11]

I purchased my Zoas from my LFS about a month ago, they looked great! As soon as they got to my tank, same as store temp very similar perimeters and they don't want to open, I've moved them around, to different light and flow options, still nothing. No at this point they're starting to release from the LR. They're under the Marine Orbit LED, white is at 60 percent and blue at 100 at max intensity. I have a 20 long, the deepest point of my tank is only 12 inches...don't know what to do..help? Thanks!!

The picture below shows the Zoas, just left of mr grumpy gills

I had a similar problem in my tank. Ended up turning the led's down to 80% blue and 20% white. I've found the reds, oranges and pink zoa's can handle much more light than the greens and browns. If you have some green water, and or food for filter feeders you might be able to entice them to open to feed. It also might help if you have a slightly shaded spot for them depending on the color. I'd reglue the stragglers to plugs or rocks so they don't end up behind the rocks.

Is it possible they are getting stung from something? Maybe a little chemical warfare?
I wish I was more helpful. Sorry and good luck.

They are melting. . most possible reason is too much light but there can be numerous other reasons too ..

best thing to do is dip em in peroxide ( i do 1 : 4 ratio of hydrogen peroxide to tank water) and set them in a very shaded area .. will take cpl weeks to come back

I would move them away from the Euphyllia/Frog Spawn just to rule that out.

Assuming your chemical parameters are reasonable, my guess is your lights are too intense. 100% intensity for a tank that is only 12" deep might be too much intensity for some SPS even, not to mention a zoa. I have very little experience personally by the way, I just know what I read.

Have you inspected them closely for snails that eat zoa's. I've had them come in on polyp rocks several times in the past.

Which led lights did you have? When I turn it down to those settings on my orbit marine it is pretty blue and really low light... Thanks I'll have to try to bribe them to open haha

Water perimeters are on point, the frogspawn is no where near nor is any other coral...

I will give this a shot when I get home! I was told that last week but it was from a very trusting source so I held off, but I've now seen its pretty common. Thanks!

I have a mix of diy fixtures and cheap Chinese ones. I found my sps weren't opening until I added more lights. Went up to 1000watts then began lowering whites until I liked the coral response the most.
