Zoa always half open

[tenderfoot]

now I have scoured the net about why this is happening and I can only assume it is from pods...

Forgive my horrible pictures as I am using a droid bionic to capture them but the story goes like this. I have 3 colonies of zoas in the jbj 3 gallon pico using a evil par38 LED with 20k and all other corals are doing exceptional. I do, however have 2 colonies of hornets purple and red that just cant seem to be happy ever. This I find strange because they were single polyps purchased from my LFS and now the reds have 13 and the yellows have 7 and a new one forming.

Despite them being seemingly half happy or unhappy they continue to grow.



and these are the purples





I have dipped them in fresh water also freshwater and lugols... Help please!

Iknow that when mine are putting out new polyps they don't always look their best. They actually look a lot like yours. I would guess that yours are doing the same.

Another possibility could be too much light. I know those PAR38s put out a good amount of light. Maybe it's a bit much for them?

More info on your setup may help. What are your params? What other coral do you have in there? Any fish?

They look normal to me.
I would leave the zoas alone for a while.

Anyone have any experience with zoas under LEDs? I have the kessil a150 and have a similar problem

I'm using the kessel and par 38 over my 34 gallon Solana. My zoas do best on the sides rather than right in the middle. As soon as I put them in the center they close up and need time to recover. Palys seem fine in the middle though.

I have used the par38's and an led fixture and found that you really have to acclimate the zoas to them. I had more issues with the par 38's on my nano because i didn't have a dimmer. So i had to slowly lower the bulbs to where i wanted them.
