Zoas not opening...

[MattL]

So I have a bunch of zoas and the most expensive ones are not opening all of a sudden, but the common ones are doing as good as ever. I tried a dip, no change. Thoughts or ideas please. Btw water prams are great with no change.

How long have you had them? If you have had them a long time maybe try a different flow/light location higher or lower (opposite) of what you have them in now. Also if you move em I'd give them time to adjust in the new location to try and open before moving again.

They have been stable for a while. No change in placement for a few weeks.

I'm still a none believer, but there have been threads on other sites that state a lack of amino acids will cause them to not open.

If others are open, and these aren't - best leave them alone. Amonchak is right about the flow and light. If after a few more days they don't open, I'd recommend moving them. My 2cents anyhow.

If mine don't open after a few days I move them to a new spot with less flow.

Have you moved any rocks or added any to your tank? I was scratching my head just last week when the same thing happened. Turns out moving a rock on the opposite side of the tank by about 2" was enough to alter the flow so that quite a few of my zoa frags were getting hit by direct flow. The rock just happened to "funnel" the flow right over them and ****ed them off.

It's funny how some like flow and some don't. I have my MP40 pounding on some and they don't mind a bit but others get even a bit of that and they stay closed. I have moved my new frags to the opposite side of my MP40 to acclimate until they open.

So the ones who closed up are , fruit loops and bam bams.
