zoa and palys stretching for light

[homerclease]

I have some zoas and palys that (strech) for light.. their stalks get really long. I have others that are acting just fine... I tried to upload a pic but I am having some issues with it. Anybody seen or heard of anything like that?

They want more light... what lighting do you have

I was asking for a friend's tank. He has a radion xr15 gen 3 pro. He has a 60 gallon cube.. trying to get him to go to the xr30 but he wont.. I thought it was a light issue.

I have heard the term deep water zoa and didn't understand it. Is there a way to tell/know which zoas are deep water? Is there different treatment for them?
