Zoas growing up

[thiagoetto]

Hi,
These are my zoas/Pali. They are growing up, though not spreading. Pretty sure they receive enough light once I have well-going SPS in the tank.
Does anyone guess what could be causing it?

They are stretching for light. I'd move that colony up a bit.

AOG zoas tend to like a little higher light. Slowly move them up, not a bunch at a time to help them adjust to the new par. You'll see the stalks shrink down, usually I move them up and wait a week or two to see how they react.

Light deficiency. You probably need more intensity and better spectrum. Study about light before you change anything! Go slow!! To know about your particular light fixture is a must!
Good luck!
