New zoa won't open

[jong11]

I got some new corals yesterday. One frag colony of zoas opened as soon as the lights came on for about 5 hours. Then they all slowly closed up before lights out and haven't opened since. Lights are now on and still closed. I have a led par bulb. All the other zoas in the tank look happy. I can't seem to figure it out. Any advise?

LEDs are quite strong, maybe they're closed up because of it. Is it placed in bottom of the tank?

What lights were they under in the old tank? You have to be pretty careful with new corals and LEDs. Light acclimation is a most exspecially if the coral came from a tank with less intense light. id say 90%of coral death from LEds i see are from too intense light and not acclimating new corals to the LEDs

I have 5 AI Sol Blues over my 180, with a TON of zoas, some exotics 30+$ a polyp.. Anyways, my tank is divided into three sections/dividers or support braces.. 6ftx2ftx2ft. Two of those sections have two AI Modules, and my third has just one. This gives me a chance to use the low lighting section to acclimate corals. When I give them enough time, I let the corals decide, I start to move the corals to a more light intensive area...

Obviously this might not work for you, but I did this after buying these new lights because I nuked 200$ in coral because of the intense LED's..

A par meter is always a reefers best friend too

Sorry to hear.

Do you have a picture?

Were they on frag plugs?

How many polyps on it?

Was the plug fresh white or aged from maybe algae, coralline etc?

Were they shipped or picked up?
