They are stretching out for light because they aren't getting enough. You can try to move them up higher, if that doesn't work you may need a stronger light.

What kind of light do you have? What are your water parameters?

 

[CleverBs]

You need high light. Possibly clean your light from salt creep. My zoas do this when I get to much salt creep on my light and I know it's time to clean it.

I was wondering the same thing.

That base rock looks brand new too, are you just cycling your tank?

 

[Gregcoyote]

No where near enough data to make any observations. Lighting used? Water quality? Current and flow? All these things will affect zoas.

I have a coralife 150 watt metal halide HQI
on 27 gallon cube tank
My tank has been cycled for over a month now
Water parameters are calcium is 450, alkalinity 1300, ph 7.8
Nitrite 0
Nitrate <20

What about circulation? And where in the tAnk are the zoas placed? What are the dimensions of the tank?

 

[Gregcoyote]

Even a month later the tank will bounce around a bit. Ph is a bit low and nitrates are a bit high. Are you using high grade (lots of calcium) salt mix?
Flow is very important to zoas, you may need to experiment with that. What are your temp readings with the MH on?

 

[Flow863]

I get my saltwater from my lfs
And the temp stays at around 79 degrees
I jus moved them higher in my tank with more flow
Hopefully it helps

Flow means as much as proper lighting does. Sometimes they take a while to adjust.
