How to get zoas to grow big

[ld762]

I know zoas come in different types, some are big and some are tiny. I have seen some zoas of the same type (ie: scrambled eggs) that are of different polyp sizes; some are big and some are small. And I am not talking about new polyps just popping up; I am talking about fully matured polyps.

Is there any trick to get them to grow big in diameter?

i think if they are comfortable in general in your tank chemical, flow , light they grove big, I had some grow but stay small until I moved them to another spot in same tank so in 2 weeks they doubled no joke in size
